USB Audio and Recording on the Tab S2 9.7 LTE and others. ..... - Galaxy Tab S2 Q&A, Help & Troubleshooting

Hi there,
I don't trust my tired eyes,as I saw on Samsung store, that Soundcamp is available again for tab s2. And it works very fine. Very low latency on the instruments, wav export. But no quantize tool.
I tested my audio interfaces too. My guitar Rig US, no probs with amplitube. And my Native instruments komplete audio 6 works also fine. Great.
But again, there is no charging and USB support possible at the same time. So, the time, to work with your interface is as long, the battery works.
OK, the battery is very good, but why, the hell is the problem to do 1 pin more ob the USB port to charge at same time as using? Or a separate charging port? Or USB? Or whateverelsei****inwanttoworklikeanotebookwithit ?
Tomorrow I get from davy from the programmers team of "Audio evolution",in my eyes the best daw for android, a new test version, with a drum pattern editor and much others news to test.
Audio recording comes step by step to android, and the latency problems are even lower since android 5.0 . But more tools are needed, and the Samsung professional audio isn't the right way to go. OK, for Samsung apps,it's ink, and it works well on Soundcamp without any interface. But for developers,it's isn't attractive to use a sdk (that Samsung offers on their site for developers) ,that only supports one devices brand,and this only, if it's running Android 5+ .
Audio evolution got their own drivers, that support over 300 interfaces and devices. But unfortunately , it don't work as good on Samsung, latency get low enough to work without an interface, if you want to use the virtual instruments. .....
Maybe the programmers see any chance to promise optimize it more for this device. It have enough power to do audio recording on the way. ......
Do anyone also want to recording audio? What are you'r experience?

First, S2 habe enough low latency, to play with virtual keys instruments in Audio evolution. .....that's great. ....you have to set native sample rate of s2 tab (48khz),in prefs to OpenGls mode and the buffer size to native. ...that works. .......but yesterday, i do a test with connected lan, charger, usb audio interface, usb keyboard at the sake time to the tab, start audio evolution, and. ....it works like a charm. .....can use the keys, playback over interface, device is charging, and i have lan connection. ......great

Audio Extractor for $ OR Is it possible ROOT for simultaneous cast?

My friend from South Korea sent me an early birthday gift and low and behold it was a cool Chromecast key :victory::laugh: WOW THANKS but... I have a unique setup a 180" screen and Projector. This AMAZING projector (W7000) has no audio out and no way to utilize audio from Chromecast :crying: How sad... Well I discovered these audio extractors to get audio out but frankly I would love to retain max color, 3d, and 7.1 on DD+ this is not going to be easy. Then I got to thinking how come no one has developed an app which can sync the 2 outputs (multicast) from DDWRT or other at the router / gateway. Or in another way perhaps.
Two questions remain
1) Audio extractor where can I get a cheap but good one ? (seen them exceeding 200 dollars common)
THE BIG QUESTION IS
anyone know how to do this yet or perhaps if I should sell the thing and get a different setup for these projectors I have 3. (kinda committed to the output device already hehe.):cyclops:
This is what I used because the Chromecast wasn't compatible with my TV. (I had video but no audio)
www,ebay,com/itm/291119088532 $29 - has optical audio out.
Impossible to sync audio to two separate sources that are networked...
What you really want to do is get yourself a good AV Amplifier (with HDMI Inputs), not an Audio Breakout.
You will get full Surround support and would plug the CCast into the Amp and send the video from the amp to the Projector.
To answer the second question in your subject, root won't help you here. As @Asphyx said, it's near-impossible to accurately maintain A/V sync between separate networked devices. It requires sub-second synchronization and without some other constant reference not subject to network transmission delay it's very prone to failure.

Don't want to loose the 3d though and according to Wiki (not their ad on ebay) there is no 3d until 1.4 : so how come they are advertising 1.3 with 3d ?
Ohh btw does this device work 1:1 for lag or is there a few ms' wait ?
Thanks guys this really helps

AFAIK Chromecast doesn't support 120 Hz output (so no full-res 3D), though side-by-side 3D should work on pre-HDMI 1.4 as it's not doubling the rate to get L/R.
There shouldn't be any noticeable lag introduced as it's simply a de-embed at the endpoint.

Should I go with raspberry Pi 2 as Media center

I have already got MK808 android stick, which is 1.2 GHz dual core with Mali 400 GPU.
After using it long as general purpose device, decided to convert it as media centric device, with 2.1 speaker setup
I am facing following limitations,
1. Not able to play HD/1080 videos smoothly
2. Tried USB sound card to connect it to 2.1 speaker, but quality is not good
So I started to look for alternate devices. I liked RPI 2 especially due to it's support, but before buy, I have some questions unanswered
1. Since I have 1.2 GHz device, I am just wondering with RPI 2 being 900 MHz, is it powerful enough device as media PC. Especially can we consider it for future proof (may be 3 years)? I am thinking because, I don't want to fall in situation to buy another device only after next 1 year due to RPI2 limitation.
2. When I add case, WiFi dongle, power cable, HDMI cable etc, it's going to about 75 USD. At this price, there are many choices like,
# Android stick MXIII, which seems more powerful with android support
# Dedicated media player like,
http://www.amazon.in/s/ref=nb_sb_noss_1?url=search-alias=aps&field-keywords=media+player
But I don't know, how to compare those with RPI 2 and conclude which one will be more powerful and future proof
Any suggestion?

I have been using Raspberry Pi 2 B+ for a month as media center with the Rasplex OS. I have tried 1080p, 720p and a few different formats like mp4 mkv, avi etc and they all work fine, even while seeking. The main reason for this could be that the processing/trans-coding of the video is done on the server(the files are not stored on Pi, and no HDD is connected to it.) This all works on a WiFi adapter.
If You can use Plex app on Your Android Stick and use a plex server somewhere, You won't need to buy a Pi. Although You would need to buy Plex pass to come over restriction in Android app I think.
Rpi 1 can run almost limitless video bitrate via smb share. But it has issues with very heavy audio since 1 pi's processing power is not great basically. But mines 1 still run movies with 10mbps video and 5mbps audio well. Above that it starts to buffer maybe its network bottlenecking. Audio quality via hdmi is great. I got a pi 2 just a while ago looking forward to test it with openelec. I have chromecast stick too i think that i wouldn't need rpi if i didn't had media at local share. Chromecast is far more better if u use only netflix, viaplay, youtube, popcorn, etc and can use it with android device phone/tablet.
Thanks for replies.
Has anyone connected it to 2.1 speaker system?
Because, that is my one of the aim.
Can anyone tell quality if connected to AV cable/stereo jack?
And, is it possible to get video through HDMI cable and audio through AV cable to 2.1 speaker?
Can someone, who already have similar configuration, help me out to build similar one.

How do you rate quality through AV cable out?
I believe, AV out doesn't give good quality as HDMI.
Through USB sound card on my MK808, I am loosing bass. Woofer doesn't give any sound.
I am worried, same should not be with RPI as I'll loose all fun of watching movies.
Anybody with 2.1 speaker setup hear?

Unfortunately, my LED TC has onlu audio jack. So, if I connect 2.1 system with it, I get very low volume.
So, only option to get sound from RPI AV jack.
Can you check in your system with AV jack and report the difference in output?
Any though on
RPI2 vs MXIII vs MXQ?

Composite video out quality is pretty good. On OpenELEC, playing 720p live stream Russia Today. Output is classic PAL resolution. Image quality is better than 576p SD DVB-S thru SCART with good quality sat reciever. I have big old widescreen CRT Panasonic Quintrix TV.
If you play any 720p movie, quality will be comparable to DVD player with SCART.
I dont know how is your audio input for these 2.1 speakers. Just single 3 pole 3.5mm or also separate one for subwoofer? If it need 2 connectors then you need 5.1 sound card with (usually orange) center/subwoofer connector.
I think you should turn up your headphone volume on your tv

Ideal for local media or media on a NAS but not being able to access Netflix, Hulu etc (like you can on Android) might be a bit of a put off. Shame really coz the Pi2 is more than powerful enough to support these streaming services

Mate 10 Pro LDAC Playback Quality

Hi, got a Huawei Mate 10 Pro BLA-L29 8.0.0.136(C185) and a Shanling M0 as a Bluetooth receiver. When I get them connected using LDAC, there are two menu sections where I can set the audio quality to be fed to the M0. One is the Developer Options where, apart from selecting the BT codec itself, I can set sample rate at 44.1 to 96 kHz, bit depth of 16 to 32 bits per sample, and stream bitrate at 330 to 990 kbps. These settings behave in a weird manner, always reverting to default every time I disconnect the BT or even while it's connected. The other instance is the properties of an individual BT device where I can set the LDAC playback quality to either "Optimized for audio quality" or "Balanced audio and connection quality".
Problem: if the BT device is "Optimized for audio quality", I only get decent transmission if stream bitrate is set to 660 kbps or lower in the Developer Options. Inversely, if the latter is set to 990 kbps, it only works decently if the device-specific setting is "Balanced audio and connection quality". If both are set to maximum audio quality, the playback starts gagging violently, interruptions happening up to twice a second if the phone is active and like once every five to ten seconds if the screen is off (the two devices 5 inches away from each other with nothing but air between them).
I brought the Shanling M0 to the nearest Sony store and paired it with a demo phone with LDAC audio quality set to 32/96 at 990 kbps and it worked like a charm without a single hiccup.
Anyone else has this issue and/or aware of a fix?
I have been to a number of stores since the original post and was able to pair my Shanling M0 to various devices:
1. Huawei P20, Android 8.1, Bluetooth 4.2 - same problem.
2. Samsung Galaxy S9+, Android 8.0, Bluetooth 5.0 - no problem.
3. Samsung Galaxy A6, Android 8.0, Bluetooth 4.2 - no problem.
Apparently, Android version is not responsible for the malfunction, neither is Bluetooth version. It's the manufacturer.
Crap, crossing fingers about having this issue fixed. Have you reported it to Huawei customer service and Shanling's one ?
Thank you for the feedback. I'm interested in this small DAP (nostalgic for my beloved Sansa Clip), even if I'm quite sure I probably won't use the Shanling M0 as BT receiver.

If you ask me, you should just grab your money and go get it, because it works fine with other phones than Huawei. Even with mine, if I set it to "Balanced audio and connection quality", it's doing great. Actually, the LDAC standard bitrate of 660 kbps is amply sufficient to deliver music from major streaming services like Google Play Music. Whatever the problem is, I don't believe it's Shanling's fault, because the intensity of gagging depends heavily on whether the phone screen is on or off, which has nothing to do with connection quality.
As to the DAP itself, I find its sound signature and stage presentation nothing short of amazing, at least on par with my favorite Hidizs AP100 and far better than vivo Xplay6 or anything else I tried. Sansa Clip+ is nowhere near. The way I feel right now, I'm far more likely to ditch the Huawei phone than the Shanling DAP, because there are reasonable alternatives to the former, but not the latter.

Indeed, I started following Head-fi.org's thread few weeks ago, this device looks great.
I currently own a Cowon Plenue D for more than 2 years, I'm quite happy with it: relatively small, great battery life and sound. But I'd like to have a smaller good DAP I can bring with me when I run, or simply don't want to suck smartphone's battery. I bought a Sansa Sport Clip+ (BT DAP) one year ago, crappiest DAP I ever met...
What's your battery life experience using BT head/earphones wiht this DAP ?
Hello there,
Just to share the using LDAC experience with a mate 10 pro (BLA-L29 145 (C432))
I have a Sony headsets (WH-1000XM2) and it works just fine, I'm able to use LDAC perfectly, sound is very good but you need to be close to the phone, 5m apart and it starts to break.
I know its not the same situation, but this is my experience.
Best regards.
And the volume?
Mine with my sennheiser 4.50 BT NC is very low..

I have no such experience, I only use M0 as a BT receiver with wired IEM connected to it. I never even bothered to measure battery life, since it's more than two days of my regular use, i connect it to a USB port earlier than I need to charge.

If you want to control volume on your headphones, you need to set it to maximum on the DAP. The rest of it will be the responsibility of your headphones' integrated amp - if the volume's too low, then it's just not powerful enough, there is no way a bluetooth source can fix that, as it does not transmit loudness.

Thank you very much indeed, because that's exactly the diagnostic step that I missed. Need to try that to locate the problem more precisely. Are you sure that the LDAC playback quality setting in your bluetooth device options was at "Optimized for audio quality"?

I would suggest that you go to the Shanling M0 thread on head-fi, there's a company representative on that forum who's very cooperative, you should describe your issue to him. I wish I could give you a hand, but my experience is limited to operating the volume wheel on the DAP.

Yes... it has to be... or it wont use LDAC at all... it will use APTX or something else... LDAC is only used on the setting "Optimised for audio quality".

LDAC Playback quality stuck on Best Effort, unable to change

I have a 4XL and have noticed that it is not possible to change the Bluetooth settings under developer settings. For example I have Sony WH1000 M3s and whilst it connects using LDAC it defaults to ‘Best Effort’ for LDAC quality settings and cannot be changed. It also will not let me choose another codec such as APTX-HD.
My understanding is that on Pixels (well for the Pixel 3 at least) that best effort results in a lower bitrate than SBC? So this is potentially crippling thre audio quality.
Anybody else noticed this? If so, any solution?
Lucky you.
I just picked up a pair of V-Moda Crossfade 2 Wireless Codex cans, and I can't get any other codec besides SBC working via the Developer options.
Yes, I have same and noticed that.
Trying to use AptX HD also doesn't stick. You can do it in Developer Options by messing with other BlueTooth settings first to match what AptX HD would allow but the next time I connect my headphones it's gone back to LDAC.
I think the main problem is Sony's Headphones app which defaults to LDAC (of course as it's Sony's proprietary codec!) and lack of controls to use other codecs and settings.
In that app I have Sound Quality preference selected at the bottom which actually may be using a better quality setting, it just isn't reflected in what you see in the Developer Options settings.
Interesting, the LDAC issue might not be fixable but maybe removing the Sony app will allow aptx-hd to be selectable?
Btw, other droids are not much better. Samsung’s do let you change the setting but revert back to best effort every time you connect. Only the P30 pro seems to remember but then Huawei have put that option into the normal settings rather than leave it buried in developer settings.

On the Samsung Note 10+ 5G now allows selection of best audio quality for LDAC, but the the connection quality between the Sony XM3s and the 10+ is very poor. All pointless.
Kind of begs the question as to how much the on paper advantage android has with LDAC and APTX-HD really counts in the real world.
Honestly, irrespective of codecs I actually think iPhones sound better over Bluetooth which is a massive shame and totally unnecessary.

Would the headphones even work without the app? I haven't tried.
Would they default to some built-in setting without the app to communicate with?
You go first!
Headphones definitely work without the app, I have used them before on a previous phone and forgot to install it.
BTW everything works as it should the P30 pro, you do not even have to go into developer settings to change it.

I'm also unable to get my 4XL into 909/990 kbps mode, but I noticed that Pixel 4 XL seems to default to 606/660 kbps mode, which is more or less comparable to aptX HD(576 kbps). And I know for a fact that this is not an issue with the headphones or the app, since I get 909/990 when I connect the same headphones to Sony's Android devices with the app installed via LDAC Bluetooth connection.
Interesting, my 4xl defaults (and is stuck in) to best effort not 660 balanced mode.
I think on Pixels best effort is circa 330 kbps

Always defaults to Best Effort here which is 330kbps for Pixel 3 according to https://www.soundguys.com/understanding-bluetooth-codecs-15352/
I can set it to something else and when I next go into Developer Options it's back to Best Effort! Same with setting the codec to something else.
Pixel 4's best effort seems to be 606/660, not 303/330. At least that's what the bug report says. If the 3 only connects at 303/330, that's gonna be a problem when using new BT5.0 stuff from Sony. They're using an MTK chip for BT5.0, so no aptX, only SBC, AAC and LDAC on BT5 stuff from Sony.

Out of interest, how have you been able to tell the bitrate it used for best effort?

i was under the impression that this is relative to the device you connect.
Hi All,
There is a fix. I have the Sony WH 1000mx3 headphones and the One Plus 7 pro 12/256 fully updated. Enable developer options in settings on your Android phone if you haven't already done so. Remove then reinstall the Sony connect app (your previous settings will remain after the reinstall). Follow the prompt from the Sony app to connect your headphones by bluetooth. When the headphones are connected go to settings, Bluetooth and Device connection, then Bluetooth. Under available media devices you should see your Sony WH 1000XM3 headphones active. Click the settings icon to the right. Turn off HE audio: LDAC.
Open your preferred music streaming application (Tidal) and play music, verify that the headphones are operating. Go to system, then Developer options. Under Networking scroll down to the Bluetooth settings. The Bluetooth audio LDAC Codec: playback quality has now defaulted to Streaming Optimized for Audio Quality. You can now adjust the Audio Codec, Sample rate, and Bits Per Sample to your preference. The settings will stay and won't need to be reapplied.
I hope this helps.

bumping this thread, because I was looking for an answer, this was the closest to it.
I decided to dump the logs with adb, and found that my Pixel 4XL, latest and greatest updates as of May 2020, is negotiating 990 LDAC, with the 1000XM3s.
I can use the dev options to push it around to 330/660/990.
No matter what setting I use prior, if I go to auto, it will negotiate to 990, which is pretty awesome. I have not tested to see if it drops off if you walk away from the phone, but given the BT range I get with LDAC, I'm assuming not.

That's good news, thank you for that.
How to know the bit rate is 990 using best adaptive?

Limit the max sample rate to 48kHz?

Hi, is there a way of limiting the sample rate to 48kHz in Android 10 (AOSP Rom)?
I'm using a USB-C to headphone dongle and according to the developer, Viper4Android doesn't support a sample rate greater than 48kHz, so my current driver status is abnormal. Note that my bluetooth headphones work fine.
In system/etc, I have a audio_policy.conf, but not an audio_policy_configuration.xml ( https://source.android.com/devices/audio/implement-policy )
Any alternative ways of limiting the sample rate would be much appreciated.
The mixer in Android downsamples everything to 44100Hz anyway, so that is probably not the issue.
It won't ever go past the above value other than the case where you use an application that creates a pass-through between the DAC (whether that is the internal one by Qualcomm or an external dongle one) and the output, thus offering bitperfect quality

Thanks for your response - do you have any other ideas why viper doesn't work?
Absolutely none, it's old and unmaintained as far as I remember. I am unsure of the compatibility of the newer fork of it as well. Good luck getting it to work
I mean you can try jdsp
Yeah James DSP does work actually, but it's missing a few features. It seems the only way of fixing this issue is using a passive headphone adapter, which aren't that common on amazon at least.
