Bad Voice quality when phoning - LineageOS Questions & Answers

Hi guys,
I have currecntly LineageOS Build 14.1 20170410 installed on my Nexus 6P and the quality of my voice during calls seems to be pretty bad. It's propably coming from installing Viper/Dolby Atmos for trial. I think these change the audio.conf file or something and that's creating this issue.
I already tried reflashing LineageOS as well as the vendor.img but there is no change.
It seems to only be a problem for calls. I tried a recording and it's okay.
Has anyone a suggestion how to solve this?
I thought about extracting some files from the factory image but i'm have no clue which files.

Hey Gus,
got the same problem with my galaxy s4 mini and LineageOS 14.1-20180107-serranoltex all that in the micro-g-version (that already was a slight improvement compared to the lineage version without any g-apps....)
any idea?
thanks in advance,
leo

HTC One M8 Sound Output Issue Causes App To Crash

Hi all,
Was wondering if anyone else is having this problem? I got affected with this issue since last week. Tried flashing few roms, but apparently did not solve my audio issue. Hope it has nothing to do with the hardware speaker or mic. Whenever i tried to play music or video, the app would just crash. No matter where i'm playing from. Browser, Chrome, Gallery, Sound Recorder and everything else.
I've done all the necessary software changes, could it be a hardware issue that is causing this?
Roms that i've tried.
1. ResurrectionRemix-M-v5.6.0-20151217-m8 (Android 6.0.1)
2. cm-12.1-20151117-SNAPSHOT-YOG7DAO1K1-m8 (Android 5.1.1 Stable)
3. cm-12.1-20151125-NIGHTLY-m8 (Android 5.1.1 Nightly)

Laggy video playback and no audio

Hi all, after I flash any rom (ressurection remix or lineage os 14.1) video lags in YouTube and there is no audio when it does play. Also Spotify has no audio and same with Facebook videos etc.
This is obviously a system wide thing so if someone could help me I'd greatly appreciate it as I can't use my phone for what id normally use it for. Many thanks in advance.
Hi, I have the same problem, only I am using stock rom 9.2.3.0 can't find any reason why this happened. All videos stutter with no audio. Before I updated to newest release it was all working.

Sorry for the late response but I have the solution worked perfect for me. Follow this and then reboot.

He means build prop editor too.
I have the same problem with LOS 16.
Unfortunately buildprop cannot find an attribute called audio.deep_buffer.media.
What else can I do?
Same problem happened to me yesterday (didn't hear the alarm clock cause there was no sound ). I'm on the same version of unofficial rr16 from 4 months and this issue began yesterday. If i reboot the phone the problem disappear for some time, then comes back again.
P.S. i don't have audio.deep_buffer.media in my build prop too
Lol you saved me. I am using a miui gsi right now, I also didn't have the prop. Simply download a root explorer like mixplorer, go to /system/build.prop and open it with text editor. Then add: audio.deep_buffer.media=false

[FIX] [AOSP] Improve audio recording in video and calls

After devs changed fluencetype to fluence in build.prop for low incall volume, noise cancellation is so agressive. This fix solve distortion that you can find in your recordings.
- Tested in firmware 9.5.30
- Tested in Pixel Experience CAF and Vortex
Instructions:
- Download NoiseSuppresionMod.zip
- Reboot to recovery
- Flash NoiseSuppresionMod.zip
- Reboot to system
It MAYBE works in MIUI.
If devs want to fix it in their ROMs, they need to replace audio_platform_info and mixer_paths in /vendor/etc
Thanks to @Zile995 . He solved it in mido and helped me to do it in lavender.
Also, thanks to @letsmakecakes. He helped me to make flashable zip.

whats this for?
Wish I had this a couple of weeks ago when I was at Primavera Sound festival! All the audio of the videos i recorded was terrible :/
Anyway, can anyone confirm this works on stock (rooted) MIUI? Thanks!
I flashed it but have yet to test it. Before flashing this I made a phone call and I could barely hear the person on the phone. That's odd because my hearing is amazing.
Thanks for the amazing work!! Nothing try in miui stock?

Hello to all,
Thank you for your work.
Someone knows if on Lineage Rom it works this patch?
Thank you in advance.
Thanks for the mod, it's working on Lineage but the recorded audio is quite low in terms of volume.
If it could be possible to increase it a little bit at least it would be perfect, thanks again!
Hello, i got some questions about this patch:
1. Do i need to root my device to apply it (flash it)?
2. Someone already tried on a Stock ROM with MIUI?
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?
Thank you friends.

Not necessarily, but you have to unlock it in order to have a custom recovery
2. Someone already tried on a Stock ROM with MIUI?
Not that I know of
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?
It's in the OP, as I already said you must have a custom recovery which means unlocked bootloader
Thank you friends.

@danielh1402 could make the previous file available, named lavender-aosp-audio-fix.zip This new file didn't work, but the old one worked. thank you!
Which exact changes were made on the mixer_paths and audio_platform_info files?
I'm trying to fix a similar audio issue on my Mi 9 SE, if you could tell me the changes it may help me a lot.
Thanks.

On Pixel Experience Official this is stoping the video (and sometimes closing the camera) while recording. How do i do to uninstall it?
On Pixel Experience doesn't work, the recorded audio is still awful. And mostly it stops the video recording.
Yesterday I was watching a video recorded with the smartphone and I noticed that the microphones are very sensitive.. maybe they're simply bad adjusted and all we need to do is to lower the gain a little bit.. I don't know. Still hoping for a V2 for this mod.
Tried on Havoc OS. Everything became much worse after flashing this "improvement", nobody could make out what I was saying.
As factory reset did not work and there is no option to uninstall the mod I had to do flashing of a new os with dalvik, cashe and data wiping.
So be aware!
Thanks! This mod work fine in Lineage OS 16 for Redmi Note 6 Pro. The mic volume was very low. Now is great.
Not working in Havoc 3.4. Made the situation worse. No option to uninstall it.
Doing reinstall of entire ROM now.

xt-1922-9 no sound from speaker, tried all custom rom and cannot flash stock rom, HELP PLEASE!

I tried all custom roms possible and no one have sound, only with earphones.
I'm pretty sure it's note mo phone defective because was working before and didnt drop on the floor.
Any help would be immensely appreciated.
Thanks.
I have the same phone and have discovered the same problem after flashing any of the Android 11 custom ROM. No sound from speaker/ringer/media (except headphone jack). I found one suggested solution here, the last reply to the AOSPK ROM thread. The solution was to place 4 files into vendor/etc. I tried that and sure enough I got sound back with those ROMs but it broke the phone call function, couldn't make calls, dialers just ended call as soon as I tried to connect. Maybe this will work for someone else. Maybe someone else has a better solution. I'll try just replacing one file at a time and see if I can figure it out. If you find a solution let us know.

Oh and the easiest way to get back to stock is to use the Motorola Rescue assistant tool here. Just put your phone into bootloader mode and the Motorola tool will detect the phone, download the latest stock firmware and restore the phone.
Okay, I found the fix. From stock I installed AOSPExtended ROM from the Moto G6 Play forum. Initially everything seemed to work but no audio.
The fix reported in my last post, linked to the Telegram group was:
"For sound, add these 4 files to vendor/etc"
mixer_paths.xml
audio_platform_info.xml
audio_platform_info_jeter_p0.xml
mixer_paths_jeter_p0.xml
"
Copying all 4 files caused audio to work but cell calling broke.
Copy only the first 2 files without 'jeter_p0' in the name and audio was fixed and nothing else broke. Happy now. I assume this will fix the same problem with all the Android 11 roms I installed that caused this problem.

I'm a n00b so I hope you can please excuse my ignorance but how did you copy the files to that folder? And how did you get the files from the source? Also does it fix the rotation? as I have a rotation problem as well
OK its within TWRP didn't know that, file manager

Hi, friend.
I tried your solution, but it did not work on my phone, jeter xt-1922-9, i flashed pixel experience plus or lineage os 18.1, no one working on audio. no sound incoming call, no sound on youtube video.

No sound during calls in Lineage OS 16 (for Galaxy Note 3)

Greetings!
I am fairly new to rooting and I just rooted my first phone (yay!). However, there seems to be a problem with the call. There is no sound during call at all (including the dialing tone). I tried every fix I could find, including changing "persist.vendor.audio.fluence.voicecall=false" and "ro.vendor.audio.sdk.fluencetype=none". The problem isn't fixed. I was hoping if anyone can tell me what I should do. Btw my LineageOS version is 16.0-20190621-UNOFFICIAL-hlte and android version is 9.
