[Q] Problems with Switching audio

Hi Everyone,
I have a weird problem. I tried installing skype from play store yesterday and DSPPack for player Pro and ever since i am having this weird problem.
1) When i plug in a Headset/Earphones the phone does not recognize it. The Audio from the phone calls continues through the earpiece and Music is routed to the Speaker
2) When i restart the phone with the Headset/Earphones plugged in, all the audio is played only through the Headset/Earphones (removing them the audio is not routed back to the earpiece or Speakers)
3) I found this app called SoundAbout, using this app i am able to switch between the Earpiece/Speaker and Earphones/Headset.
Can someone guide me as to how to fix this problem. I have done factory reset twice already but of no use
Thanks and regards
Sanjay

I'm on stock JB retail.EU too. I tried the features that make you problems to find out whether I've got any issue. Both video and Skype through headphones work normal, sound is transmitted via headphones. I don't use any market video player I suppose that you use MX Video Player. Try with stock player, you'll have excellent and smooth video playing. If you want to use other player because of subtitles, I recommend BSPlayer.
But what is important for the beginning is to eliminitate possible cause of your troubles. I suggest you to try these:
1. Inspect how are headphones connected. Thin click is to be heard when connected right. They shall not be inserted less and not beyond this click.
2. If you have bluetooth headphones or you can borrow them (stereo not calling headset) try whether you have the same problem with them.
3. Remove video player and check if the problem still exist with Skype.

1) The problem is not related to Hardware, otherwise SoundAbout would not work
2) Same problem with blue tooth headphones
3) I have removed skype, Player Pro
I installed Player Pro and not MX Player
I even made a factory reset (Settings - Privacy - Factory data reset).
I again made a factory reset now and as i mentioned before... the phone does not detect anything plugged into the Audio Jack. If i restart the phone with something plugged in the audio jack, all volume is routed only through the audio jack (if remove the plug, there is no audio from the earpice or built in loudspeaker) and i have to restart the phone again

Then is it obviously that you have problem with the system (JB or kernel). As I mentioned I have the identical system and no issues with voice switching. You could try to flasIt the JB once more but I wouldn't recommend. Since you have practicaly new phone the most logical solution is to bring it to the service. Its better that the service take the risk of succesful flash and it is usually done really fast.

Could you please tell me how to flash JB again to the phone?

Bluetooth Audio Issue

Today I noticed a bug with BT audio and Navigation.
I have BT in my car so I connected my phone and started up my tunes like I always do and everything worked fine.
I needed to use Google Maps Navigation and on my previous phones using Nav with music playing (google play music streaming) worked fine.
Today I noticed that when ever Nav had an instruction for me, the music volume would drop, but no audio from Nav would play.
On my bluetooth profile on the phone I have phone and media audio running through bluetooth.
Anyone have a solution for me?

Unrelated question. How is the audio quality over bluetooth? Any noticeable difference when it's wired as opposed to over bt?

I can't speak on the potential bluetooth through car issue, but I have no issues with using a Supertooth 'visor' device, and at least in my opinion, the audio is of reasonable quality (though I've not tried to play music over it, just nav, and the occasional notification noises while on the drive).

Dude, lol, start your own thread. Don't hijack someone elses.

Nobody? If my replacement does this too the phone will have to go back. I use bt audio and Navigation together all the time

In an effort to apologize for highjacking your thread:
If no music is playing, do you hear the nav instructions?
Maybe try toggling the voice instructions from the menu of the navigation app while it's running?
I don't think this will work, but maybe going into the settings page that has the three volume sliders and try moving those around to see if you get different results?
Maybe there's an issue with text-to-speech, but I'm not positive on how to fix this. I know there's some stuff in the settings section and you can install a third party TTS system, but no idea if that would help.
I think it goes without saying, have you tried re installing google maps?

Nope. Oddly enough the problem went away. Everything is fine now

[Q] Jack Issue

Hi, it's my 1st post on xda forums and my english is very bad (I'm French) so pls forgive me for that.
My problem is a bit strange, my nexus doesn't accept all the headphones jack... I mean, before, I was listening music with my headphone (Philips Fidelio M1) when I'm outside, and at home I use my speakers 2.1 (Focal xs) with a standard jack on both. But, since a few days, the jack from the Focal XS is not working with my nexus 6 (the music comes out from the Nexus's speakers), but works fine with other devices and the jack from my headphones is still working perfectly...
I have to precise that I'm using Viper4android but It was working fine with it before.
Thank you for your answers, have a good day.

Sometimes you don't have it set well enough and you have to give it another push to make sure it connects. Also you can try a reboot. I have had the same issues, but with bluetooth. Sometimes, even with bluetooth connected, the song will play through the speakers. I think it's just a lollipop bug. Usually a reboot fixes it for me.

Unfortunately it's not as simple as that, I tried a reboot and the problem is still present. I have to be more precise : I tried several times and the jack from the speakers 2.1 never works and the jack from my headphones always works. It's so strange... I tried with my sister's headphones and is still working but on another external speakers the problem is back. I tried also to connect it in a friend's car and it worked perfectly fine. It seems like not all the 3.5 jacks works... But before I didn't have this problem.

Are you always using the same cable for external speakers? Maybe it is the cable?

Like I said... The cable is working perfectly fine with any other devices (my PC, and others phone for example).

I had the same issue with when I had viper installed. Uninstalled it and all is fine now

Ok... Ty for your answer, It must be the same bug for me... But I really love v4a, I hope they will fix that soon.

Had the same problem with viper. Is your problem still persistent after uninstalling v4a?

I didn't uninstall it for the moment, I can't say...

Yep same issue with viper/ uninstalled re flashed ROM everything normal.

Just to add to this... I'm on COG2 and still having the headphone jack issue....im using Viper as well. The only reason I use headphones is because Viper makes it sound so good! Haha. Strange issue...

CM 12.1 droid turbo Bluetooth calling not working

I recently flashed CyanogenMod 12.1 nightly on my droid turbo. I Have had a good user experience so far, although there is only one issue that is really effecting my decision of using this ROM as my daily driver. My phone has no audio during Bluetooth calling and the microphone is not working as well. I'm not sure if this is a known issue or if there is a fix available at this time. I would greatly appreciate any responses in this thread troubleshooting the issue, so we can all resume safe hands-free driving.

Do you happen to be using the 11/29 nightly? I haven't tried any other newer release yet, but I have been able to successfully connect via bluetooth to my car and stream audio. I've had no indication of it failing. The one thing that got me at first when connecting to my car and streaming was that bluetooth has it's own volume control (which I turned up to maximum on my phone). I'm not sure that would explain the microphone though (if it's even related to your issue).

Depends on the bluetooth device you have. My Jawbone ICON earpiece works fine, and my Pioneer car stereo makes calls fine. Other people have had some issues. The dev says he needs a logcat for missing bluetooth configurations.

Also for the bluetooth sound not playing issues, I'll need a logcat for those, since it's possibly a missing configuration for some of them.

And you've gone into the phone audio settings (when it's connected) to make sure your mic audio, etc wasn't turned down? Audio settings change when Bluetooth is connected...
I use Volume Control Plus and put a shortcut on the desktop so I have quick access to all the phone volume settings.

yes I have made sure it is turned up on the head unit and the phone when connected and I have also tested when in a call selecting Bluetooth toggling back and forth from ear piece speaker but no change

This is why I ditched cm12.1 and went back to stock. My bt headset worked with music but no phone calls.

External Microphone on 3.5MM audio Jack not working - Headphones worked!

Hello Guys,
I been searching alot in the forum and I can't seems to find a solution for this yet. Maybe I got too confuse after reading some threads here.
nevertheless, I just wanted to make sure that my external Microphone would work with the 3.5mm Audio input jack. I have tested the same mic with the correct cable and it works with my 1Plus5T / Samsung Note8 how ever no luck with the K20Pro.
Do I need to root the phone and use Magisk to fix this issue?
I am currently on INDIA Raphaline rom 10.3.5 I believe
please don't shot me guys.

I just received my Mi 9T Pro a few days ago and was researching this. Don't have a mic yet so haven't been able to try it. I guess evidently it will work with Open Camera as there's a setting for that. But I'm trying to see if it works with Gcam mods. I found this video but it's for the Gcam stock app. https://www.youtube.com/watch?v=-cNyep1vADY Please let us know if you find anything.

Just got my Mi 9T Pro a week ago and just bought a mic the other day but haven't had a chance to try it yet. I'll let you know. I think Open Camera has a setting for external mics. Gcam has a setting that pops up when a mic is inserted, but that's the stock software. Not sure if Gcam mods do. See above for video link.
Just saw this article that says an external mic won't work. Not sure how accurate it is. https://timesofindia.indiatimes.com...ortant-video-feature/articleshow/70339311.cms

Same issue here. Discord with an external mic is not working, but in the miui recorder app it is. Did you try that?
I'm pretty sure its a MIUI bug since one year ago the poco f1 had exactly the same issue and it got fixed via update.

Sorry for the confusion. So my phone Mic is fine. When i plug in my headphones ( Samsung akg s8 ones with a external mic), the phone detects the headphones with external mic but the mic on the headphones doesn't work but I can hear music, voice calls through my headphones. Just the other person can't hear me through the headphone mic. Tried with the recorder app etc. The mic on the headphone doesn't work
I have tried 2 samsung headphones and 1 apple headphones. All with the same issue.
Tried all the headphones on another phone and all the headphones and mic work perfectly.
Does it need specific xiaomi mi headphones to work or something?

No, definitely not. Mine is some old one from oppo find 7, I think.
Thats weird that it doesn't work for you in the recorder app though, cause for me it does. Its just voicechat applications like discord for example which don't work.. and it really annoys me.
We should definitely report it to xiaomi via the feedback section at the bottom of the settings.
edit: seems like it is a known issue already

I have been hearing different views from various folks on this forum. I have the Indian version of the K20Pro and i can confirm that the mic of an external headset (earphones or headphones) does not work. I can however listen to music and also hear the opposite person talk where i receive a call. However the opposite person cannot hear me - which is indicative that the mic does not work (or there is an issue)
On the positive side though, i flashed Revolution OS and this problem seems to have been fixed. I can now use any earphones (or headphones) to take calls and the opposite person can now hear me. I am doing an entirely clean flash (fastboot) now to check if that works on the latest Indian version too.

I suspect it is an issue with the global firmware. If may want to try some of the Chinese ones to see if that has solved this issue as most of the custom ROMs are based on the Chinese FW
Edit:
I have been running Custom MIUI with Chinese FW so far. Just did a clean fastboot of the indian version 10.3.5.0 and guess what - the mic works for calls!! Very strange as it definately did not work for me out of the box

Did you do a factory reset or something? I'm not very familiar with rooting and running fastboot so i dont feel comfortable flashing any firmwares. I'm a noob. i know :laugh:

Some feedback, but probably not what you want to hear:
Had a similar problem with Signal - old headset worked fine on HTC-U11+ stock, on the K20 pro there was no microphone (callee said no sound at all) even though headset with mic was detected. A temporary solution was to partially pull out the plug which caused the K20P to show headphones only headset connected and I guess it used the phone mic.
However I purchased a Xiaomi headset which worked fine from the start, detecting headset with microphone and callee said mic quality was much better. Seems they may have pulled an Apple move and used non-standard pin connectors
Currently on 9.9.6 Xiaomi.eu ROM, K20Pro CN version (purchased in China) 8/128Gb version.

For me it was Signal which was not working with the external headset mic, but then worked perfectly when I used the Xiaomi one. (not an advert, yet I really do like the Xiaomi headset (in-ear) and I am not unhappy that I purchsed it)
Also, and its been a long while since I had the Find 5, I seem to vaguely recall there was similar issues with headsets & micrphones on the early Find phones - maybe Xiaomi and Oppo use the same jack supplier?
