[DEV-only][WIP] ALSA BCM21553 Audio libs built from source - BroadcomCM

I've created this thread to join developers into the final audio fix for android 2.3.7. Although the prupose of this thread is to fix Audio on Android 4.0.4 we first need audio drivers source.
On all our based Android 2.3.7 ROMs we fixed audio using some AOSP Alcatel .so files (to remove Samsung lib dependency) and some Samsung .so libraries too, this is the whole list:
# Samsung audio libs
acoustics.default.so
alsa.default.so
libaudiopolicy.so
# Alcatel audio libs
libaudio.so
libaudioflinger.so
libaudioeffect_jni.so
libmediaplayerservice.so

Our device uses ALSA audio system, which is also used on stock ROM. This is related to software more than hardware, although we are not planning at the momnt to "change" this audio way. To activate ALSA audio some changes need to be done on kernel, that samsung provide to us on their kernel sources. Mostly we need to enable ALSA on device .config file:
Code:
CONFIG_BRCM_SOUND_ALSA=y
CONFIG_BRCM_SOUND_ATHENA_ALSA=y
That's not an issue as prebuilt alsa libs work, so new libs should work too. Ramdisk needs some edit too, as ALSA audio system is stored on dev/snd, and this is well defined too on our ramdisk, ueventd.rc
Code:
/dev/snd/* 0660 system audio
We realised after that that actually CyanogenMod 7.2 Sources include ALSA lib sources, what we didn't know if those sources could work with our devices. This sources build the following libs, as releated to its Android.mk files:
We can found inside hardware/sound_alsa the following sources to build
libaudio
libaudioflinguer
hw/alsa.default
hw/acoustics.default
On external/alsa-lib we can found the sources of anoher lib
libasound
And apart from that, some other audio libs such as libaudiopolicy are built inside framework/base repository, but they doesn't make any conflict. Other libs are included on Android source files.
To enable the build of those libs, using ALSA software instead af "Android default (not sure about that)". I've enabled on Boardconfig.mk the following configs:
Code:
# Audio
BOARD_USES_GENERIC_AUDIO := false
BOARD_USES_ALSA_AUDIO := true
BOARD_PREBUILT_LIBAUDIO := false # even not writted.
BUILD_WITH_ALSA_UTILS := true
This configs enable the building of those libs on their Android.mk files.
Also, I've added on device_cooperve.mk the following lines to build those hw modules releated to audio:
Code:
# Audio
PRODUCT_PACKAGES += \
alsa.default \
acoustics.default
After the build finished, and fixed some errors, AUDIO WAS WORKING, but not as expected. There were issues on Audio Routing:
Headphones are detected through system, but audio is not reproduced on headphones (speakers does)
When you make a call, sometimes you can't and phone freezes, or when you hangout the call, phone freezes.
Everything else apart from that seems to be working, even microphone, although this bugs are pretty weird, I took a look to logcat.
Code:
[COLOR="Gray"]D/AndroidRuntime( 1419): CheckJNI is OFF
I/ ( 1420): ServiceManager: 0xad50[/COLOR]
[COLOR="Red"]E/ALSALib ( 1420): external/alsa-lib/src/control/control.c:882:(snd_ctl_open_noupdate) Invalid CTL AndroidOut[/COLOR]

I/AudioFlinger( 1420): AudioFlinger's thread 0x1d978 ready to run
D/ALSAModule( 1420): route called for devices 00000002 in mode 0...
I managed to fix those errors (E/) by moddifying asound.conf, found on system/etc, adding this lines on the top and deleting old ones:
Code:
ctl.AndroidOut {
type hw
card 0 # Can replace with drivers name from /proc/asound/cards
}
ctl.AndroidIn {
type hw
card 0
}
Now logcat shows this at the moment
Code:
[COLOR="Gray"]D/AndroidRuntime( 1425): CheckJNI is OFF

D/AudioHardwareALSA( 1426): openOutputStream called for devices: 0x00000002

Actually that's the actual logcat, using headphones, and sound goes through speakers:

We must take a look if that is kernel relevant or not, as we really need this libs to work, to then start working on CyanogenMod 9.1 / Android 4.0.4 audio. Any suggestions are welcomed, although if they are from newbie or developer, don't want this thread to be spammed as others

Why this is helpfull ?
Currently we based it upon cm7.2 GB
this is because our device uses to run GB as stock.
When we figure the sources out and figure out what is part 1 or such we can adapt and try to port to CM9 so in that we can have new libs aswell.

We are fixing on 2.3.7 at the moment. Tinyalsa gives support for msm8960 chips as I can see on their sources, so we should start from 2.3.7.

Biel already said in the op that he added /dev/snd in the Ramdisk and i dont think our device use tinyalsa because With Alsa Drivers biel got sound working.

No Way To Use Audio files from other devices

Do not install this build directly to coolpad f2
you need to replace boot.img so yes porting is posssible

Just replace boot.img or something more? Could you port it or this is not so simple?

(Closed) [DEV] Samsung Crash (Issue Resolved)

Issue fixed, thanks for all the feedback and report!!!
Hello, as many of you should be aware, the latest Magisk Manager (v4.2.5) crashes only on Samsung devices.

As you might realize that according to the backtrace, non of them involves my code (which should start with com.topjohnwu.magisk.*), all of them are errors within internal and Zygote, and Samsung's multiwindow internal calls.
I am not able to identify where it crashes, and which part of the Magisk Manager code is breaking it, so of course without knowing why, I have no idea how to fix it. What makes the situation even worse is that I don't own any of the devices, so I cannot properly debug the issue.
This thread is for seeking help from users with a modern Samsung device, as I need more details.
Please describe when do the crash occurs (does splash screen even shows up?), and please upload a full logcat recording the FC.
Also, I'm looking for Samsung experts who are willing to assist me more in Samsung support for Magisk, as I never bought Sammy so I have little experience, but they seem to cause the most problems.
OT, I'm actually willing to buy a Sammy flagship, but I never buy outdated devices (older than 2 months = outdated IMO lol), so I might get the S8. The next Pixel device is already on my list, guess I'll have to spend all my tutor money on smartphones....
For Pixel support, I'll borrow my friend's Pixel XL for a couple of weeks to try things out, but this might not happen soon since school is quite busy.

Samsng Galaxy s6 edge+ SM-G928F
Rom: Audax 13 Android MM 6.0.1
Kernel: Arter97
i don't know how to provide anymore info or how to use this logcat
so if you tell me how i can gather more info i do it with pleasure

From what I can tell it only happens in the versions after 4.1 so the problem is in one of the changes after 4.1. A Wild guesses that may or may not could help is that you could set a flag that tells the Samsung framework that it isn't compatible with multi window.

Hello topjohnwu, first of all I would like to thank you for you amazing work, really it made life simplier to many of us, so on behalf of everyone using Magisk I would like to say : THANK YOU.
To answer your question, when launching Magisk Manager, yes there's the splash screen before the crash.
I've attached a logcat to my post which shows "Magisk Manager v4.2.5" behaviour when crashing.
1 - Here are some informations about my device configuration :
- Device: Galaxy S7 Edge G935F (Exynos)
- Rom: Decent Ultralite 5.0 (Android 6.0.1) Based on TouchWiz (Stock Samsung)
- Kernel: SuperStock Kernel by Tkkg1994 (It's the stock Samsung kernel with only one change : SELINUX set to Permissive instead of Enforcing)
- Root: MagiskSU
- Recovery: TWRP v3.0.2.4
2 - Now some infos about my Magisk Config :
- Modules : Emoji One, Unified Hosts Adblock, Xposed Framework (SDK 23).
- Magisk Hide : Only Snapchat (which I don't even use lol)
- Settings Enabled : BusyBox, Magisk Hide, Systemless hosts
3 - Just in case, my modules of Xposed are :
- BootManager
- GalaxyXMod
- Greenify
- Unicon
- XInternalSD
That's it, if you need any more informations, I'm here.
P.S: Myself and another member (@koko115) are experiencing and issue since Magisk v11.1 : a very long reboot time (about 1m42sec), when you'll have time, I would like to talk more about it, thank you.

Samsung Galaxy S6 (SM-G920F) Alexis Rom 8.1, Arter97: Works
Samsung Galaxy S4 (GT-I9505) AICP 12.1: Works
Samsung Galaxy Tab S (SM-T800) IronRom 3.2: Doesn't Work
Samsung Galaxy S4 Mini (GT-I9195) AICP 12.1: Will check when battery is full again
Will try to get log cats from all and the crash occurs during the splash screen of Magisk Manager
edit: Added the log files dunno if they are properly for you.

@topjohnwu - there was a problem with the refactoring you did before v4.2 with getting the application context out of the activity classes.
I made a quick fix you can find here: https://github.com/maclarsson/MagiskManager/commit/dbb7cb90529d1c9b9c95d1a0a8479c8f25464869
this works now with my S6, but certainly not the best programming style - so I leave it to you to resolve it up to your standards... :angel:

Working great (again) on my Galaxy S5 SM-G900F. Earlier (before MagiskSU) I had removed root to pass SN because Magisk had CTS profile mismatch error. But now SN is passed and I couldn't be happier. Thank you so much topjohnwu . Running RR-N rom 11 Feb 17 build with stock RR kernel, twrp 3.0.2-2

@topjohnwu
I've also noticed slow bootup times since Magisk v11.1 on a Samsung Galaxy Note 3 (stock android 5.0). It hangs at the first screen you see when you turn on the phone (before the Samsung logo screen). It eventually boots up and seems to work fine, but I didn't see this delay on earlier versions of Magisk.
Edit:
I'm using MagiskSU with no extra modules.

Release Notes
2017-10-23: Update to current cm-13 including fixes to avoid WPA2 KRACK for p6800, p6810, i815.
2017-09-12: Finally, I managed to compile a version for i815 but telephony/mobile data does not work
2017-08-23: Stabilized the new Browser, alias Gello - it formerly crashed, e.g. when opening our XDA page; Deactivated bluetooth again, since it is not done and crashed. It is still a long way: I assume I have to adopt the current Lineageos bluetooth app like Daniel did before: https://github.com/danielhk/android_packages_apps_Bluetooth. Daniels is outdated, unfortunately, cannot be used right away.
2017-07-27: Optimizations ZRAM, ISM and read_ahead also for P6810. Tried to activate bluetooth following danielhks guide. Succeeded with 3.1 in the guide - testing on command line. But in ROM it crashes when I try to activate BT via Settings.
2017-07-24: Video streaming and playback fixed with help from Bauner - native media codecs work now - meaning Youtube in preinstalled browser works now and also playing local mp4 files. I found that some optimizations (e.g. ZRAM) are not yet applied in P6810, because of a separate init.rc (-wifi) -> will be fixed in next release
2017-07-15: Auto-rotation fixed! And GPS works again, too. (got lost again in last build)
2017-07-13: Changed default orientation to Portrait. Deactivated DRM again on P6800, since mediaserver crashed in libwvdrmengine.so - and by that Youtube also broke in playing - now Youtube runs fine, but Play Movies does still not. On P6810 hopefully both works (Could not find a difference yet). Still the rotation issue is there, not from the beginning but during usage the orientation freezes somewhen...
2017-07-10: Further speed improvements, deactivating swipe in AOSP keyboard, what crashed
2017-07-09: GPS fixed, thanks to p3dboard - I was able to add a NON_PIE_SUPPORT
2017-07-07: Add several tweaks for memory usage and disk r/w speed, changed dpi to 202
2017-06-28: first release
Installation
Download the ROM and optionally GApps (ARM-6.0-pico) onto your device
Reboot tablet into TWRP recovery. I use version 3.0.2-0 here.
Wipe data, cache, dalvik/art-cache and system. Coming from stock rom, also wipe internal sd.
Flash ROM and GApps.
Reboot System. (First boot takes 5-6 minutes. Be patient.)
Root
Download SuperSU version BETA-SuperSU-v2.52.zip and install via TWRP recovery, newer releases will not work.
Not working
Bluetooth - crash when activating via Settings
DRM playback (google play movies) crashes. But after the crash starts playing on P6810!?! Currently, playback on P6810 is not smooth anymore, caused by the new codecs setup. Will investigate further.
Recent Amazon Kindle app crashes -> use an older one 4.24.0.27 or just delete libunwind.so in /data/app/...kindle directory
Internal mount of sd-card does not work -> use portable mode

thank you, downloaded & now it is under testing.

Great job, i will check back on my notes, i definitely have information on a drm playback fix, and should have notes on Bluetooth from what Daniel told me, you have to use an external Bluetooth library, and remove one of the built-in Bluetooth apks from memory via the manifest.xml...i might have a chance later today to dig out the information. I think i had the notes in the build notes on my androidfilehost area.
Actually for Drm we needed newer blob files from memory. If you know the files that need updating from my notes, grab newer copies of the files from the Galaxy s2 lineageos builds, as i think we got the l3 drm Widevine library from the android one google devices
Edit:
Just looking back at old posts to do with the Galaxy s2 phone, this is the url where they got updated widevine L3 blobs for drm Google play movies to work.

https://github.com/RonGokhale/proprietary_vendor_sony/tree/nougat/nicki
Cm 13

Look under the /proprietary/vendor/lib area for the files
Original Source for the WideVine blobs
https://github.com/TheMuppets/proprietary_vendor_sony/tree/cm-13.0/nicki/proprietary/vendor/lib

Just flashed it on my P6810, its feeling quite smooth. So far apart from the bugs noted above, I noticed that the Recent Apps view isn't showing a little image of the application, but that's not a major issue, you can still see the applications to swap between via the title bar it shows.
I've attached the Widevine L3 files from the cm13 repository link, from the Muppets github, if we replace the ones in your current build with these, that should fix the DRM playback
Edit: I just tested Google Play Movies with the existing Widevine L3 files in your build, and the Flash Season 3 played fine, the film Independance Day also played fine, so I think your Rom is fine as far as DRM playback goes.
Edit: Removed the .ZIP file, as that wasn't actually the .SO files, but html files (so if anyone downloaded the .ZIP - don't use those files). Anyway, it looks like it isn't needed
Edit: Re-uploaded ZIP with the real .SO files - Just incase you need them for testing.

Many thanks Peter! Just wanted to ask you regarding DRM since you are the expert
I already tried different approaches - media/drm always crashed...will try to integrate your suggestions once I have time to.
Currently, I still struggle with lagging once all Google apps are installed and switching between those - playing around with all these low-ram optimization hints.

Hi Frank,
Your line for the libdrmdecrypt.so was sending it to the /system/lib folder, it should go to /system/vendor/lib, and I don't think the libMc* files are needed as you say, as I have never needed them before. I've attached a flashable version of the Widevine L3 blobs for CM13, which works fine on my p6810.
so your code should read as
Code:
# drm blobs

vendor/samsung/smdk4210-tab/props/system/vendor/lib/libdrmdecrypt.so:system/vendor/lib/libdrmdecrypt.so \

Your line for the libdrmdecrypt.so was sending it to the /system/lib folder, it should go to /system/vendor/lib, and I don't think the libMc* files are needed as you say, as I have never needed them before. I've attached a flashable version of the Widevine L3 blobs for CM13, which works fine on my p6810.
so your code should read as
Code:
# drm blobs
PRODUCT_COPY_FILES += \
vendor/samsung/smdk4210-tab/props/system/vendor/lib/libdrmdecrypt.so:system/vendor/lib/libdrmdecrypt.so \
vendor/samsung/smdk4210-tab/props/system/vendor/lib/libwvm.so:system/vendor/lib/libwvm.so \
vendor/samsung/smdk4210-tab/props/system/vendor/lib/drm/libdrmwvmplugin.so:system/vendor/lib/drm/libdrmwvmplugin.so \
vendor/samsung/smdk4210-tab/props/system/vendor/lib/libwvdrm_L3.so:system/vendor/lib/libwvdrm_L3.so \
vendor/samsung/smdk4210-tab/props/system/vendor/lib/libWVStreamControlAPI_L3.so:system/vendor/lib/libWVStreamControlAPI_L3.so \

I again put the files from your zip into the device tree and updated the /vendor/samsung/smdk4210-tab/blobs.mk accordingly. Building, flashing - still it crashes when trying to play any movie with the above logcat. Any idea? Is p6800 any different in these terms to p6810? Or is it depending on the media I try to play? I have some free movies like "BIG" or "BLANK" in my collection which I test with.

Hi Frank,
I also have those free movies, big and blank, and on my P6810 they play fine. Your original Widevine L3 blobs in your p6810 rom also worked fine for me under LineageOS 13, so I think your original files were fine.
I can see from my original Slim Rom build notes, that I had put libdrmdecrypt.so in the /system/lib folder, so I think it can work from either location.
Did you try just flashing the flashable version of the Blob's I attached in the previous post after flashing your Rom? It would be interesting to see if that makes any difference, it sets the permissions on the blob files as well to 644, which they need to be to work.
There's an app called "DRM Info" that I use from the play store to confirm that it can load the Widevine DRM libraries fine.
What changes do you make between the two Rom builds (for P6810 and P6800)?
Is it just this change?
Code:
FILE: /device/samsung/smdk4210-tab/device.mk
# **************************************
# * modify file and add these contents *
# **************************************
#adjust to wifi only for p6810 - modify according to device type, p6800, i815 - same as CM 12.1 build format - check CM 12.1 library for references
# common_full_tablet_wifionly.mk - p6810
# common_full_tablet_lte.mk - p6800
Btw, I believe (but haven't tested it), that you can flash the p6810 rom on a p6800 (but you won't have Mobile Data support), and you can probably test to see if the Google Play movies works over Wifi with your p6810 build, as the original build you made for me works without the updated Widevine L3 package.
Edit: Just looked over Daniels Repository - https://github.com/danielhk/proprie...10/tree/cm-13.0/smdk4210-tab/props/system/lib
Looks like he has two files in the /system/lib, libdrmdecrypt.so and libwvm.so - so change the code to update these two files, as it could be that you have a duplicate file, one old and one new, and this is causing the issue.

Hi,
Just installed your ROM for tests. Looks promising
I have only issue with GPS. I don't see any NMEA messages.

I just tried the gps on my p6810 and see its not working. It's probably because the non-pie blob support hasn't been enabled in the linker library as the gps blob/driver is old and needs this enabled.
Frank, there's notes in my slim rom compile notes on how to do this in linker.cpp from memory, the line numbers will probably be slightly different, but the code additions should help you locate the bits that need updating.

The zip file is not flashable in TWRP, anyhow, the chmod 644 even 777 does not help. DRM Info shows that Widevine is missing. I checked for differences between p6800 and p6810. This is in /device/samsung/p80XX/ and actually in the kernel too, the
/kernel/samsung/smdk4210/arch/arm/configs/cyanogenmod_p68XX_defconfig. Every change I made is same for both, only difference is regarding RIL. Anyhow, the defconfig files differ in many areas, maybe also due to RIL - here I try a strange hack now - use the P6810 defconfig for p6800. Let's see.
Furthermore, I found a workaround for the Amazon Kindle startup crash issue. In its crash stack I found libunwind.so. Replacing libunwind.so in /data/app/com.amazon.kindle-1/lib/arm/ with the one from /system/lib -> Kindle works

Just read this thread and start play again
My P6800 flash rom with Pico Gapp but seems running not smooth and found out some common issues:
- flash SuperSU 2.82 zip through TWRP successful but not get rooted can not use Kernel app.
- play YouTube: all have stopped with black screen just few seconds after running then replay. All clips get same problem.
Have no idea but seems it needs fix more.
One more thing the brightness of screen very low even manual with brightness maximum.

Thanks! But the changes cannot directly applied to cm13.0 there were some changes. I at least found that in cm14.1 the ENABLE_NON_PIE_SUPPORT is included in the standard. Will investigate further.

- SuperSU 2.82 will not work, I updated the details on page 1
- YouTube plays fine on my P6800, tried different videos, e.g. the 4k demo videos (playing in 720p on our device ) <- do the installation with a full wipe, as described, then you should get it working - use the new version I uploaded yesterday, but it worked on the first version already.
- I also don't see the brightness thing. It is the same brightness like in TWRP recovery (auto brightness also working ... in slow steps) - maybe also due to wrong flashing method

We can install version 2.52 (https://download.chainfire.eu/743/supersu) from recovery and then update to 2.82 from Play store.

Hi Frank @frami2,
Just tested the latest build, 10/7, seems to be smoother, I seem to have more free Ram at boot, according to the program diskinfo, I have 370mb free ram, I think the last builds I had 280mb free ram. Also I tested the GPS and its working fine now on the p6810 Glad my notes helped you.
Hopefully my notes on how Daniel got the Bluetooth going (and how I got it going) might help you to fix that. From memory Daniel was working on a way under CM13 / LineageOS 13 to still have the normal Android Bluetooth stack going, along with the Bluez bluetooth stack - some sort of Compile switch from memory, a build directive. The method under CM 12.1 was to disable / remove the libraries the ASOP bluetooth stack and just enable the Bluez stack. This method probably still works, and might be the quickest way to get it going.
I've attached a screenshot of DRM info on my p6810 - this is what you should see on the p6800 when DRM is working. I know that DRM is a bit tricky, once you have all the bits in place, it just works. If it was broken on my p6810, that might make it easier for me to figure out what is wrong, but its working
Edit: tested your latest build, from July 13th, drm is still working fine on the p6810.

Just clean flash LOS build jul-13th incl. SuperSU-V2.52 and pico gapp, it is smooth than before a lot but still have some issues as below:
1. SuperSU updated to V.2.82 but poplock at SuperSU binary need to be updated.
2. Pull down status bar make screen turn to black and lock screen always black too
3. Set up screen at vertical but after reset the screen always turn to horizontal at black screen.
4. For video play: last ROMs issue are YouTube app be stopped awhile after start, YouTube and clip in browsers play OK but this ROM up side down: YouTube app play OK but video in browsers have crashed.
5. Bluetooth not active
6. ...........
Attached is video play in browsers be crashed
Edited: can not up picture from XDA app...

Hi, thanks for testing!
1. Right, install SuperSU-V2.52 and then try to update and finally update binary. The last step takes a while but always returned on my device, with success or unsuccessful - trying again after reboot it finally succeeded
2. Yes, this and the screenshots in app-drawer are missing - this is intended by the "LOW_RAM" configuration I set (https://source.android.com/devices/tech/config/low-ram)
3. I will upload a new version with fixed auto-rotation soon - still, the picture change comes with a black screen sometimes
4. Have to check the youtube in browser issue - this sounds more serious. Do you have a P6800 or P6810? Could you check the youtube app? This should play fine - and will even rotate on next version
5. Sure, had no time yet to implement ( a guide how to is there by p3dboard)

About 4. again - I'm currently running Youtube in Chrome without issues (on P6800 with deactivated DRM). it works in fullscreen and window mode.

[SM-T800] Zoom, microsoft teams, google earth closing. Cannot share screen.

Dear all,
Does anyone knows the cause or how to debug why apps like zoom or the screen sharing in microsoft teams or google hangouts close when just trying it? Google earth works for some minutes but then needs to be restarted. In microsoft teams and google hangouts I can connect to any meeting, but, if I try to share the tablet screen, the app dies.
Also, sometimes when using these meeting apps the sound just resets to zero and I need to restart the tablet. By using logcat I have seen some PCM errors.
I am actually clueless on what to do. Any help is welcomed.
Details:
Samsung Galaxy Tab S 10.5 SM T800 Chagal Wifi
Lineage Os Unofficial 14.1 Android 7.1.2 build date Fri aug 7 2020
Kernel with deathly 3.4.113
Edit: I am copying a log file that shows several errors after trying to use Google Hangouts Meets. I do not know if maybe the cores are too old and vp8 encoding is not enough
