Microphone output in video recording is a horrible buzzing noise on custom ROM - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hello! I'm a little new to custom roms and stuff (the only experience I have in custom ROMs is flashing Android 13 on a Galaxy S3),I hope it's not a big deal.
I've been having this weird issue on custom ROMs (I've tried crDroid and Pixel Experience so far) where video recordings output a horrible static and buzzing noise.
This ONLY happens while the camera is in use. Voice calls work completely fine.
I've tried different camera apps, Open Camera, I've tried GCam, hell, even Snapchat does this.
A video is attached below.
Your browser is not able to display this video.
I might try flashing back to stock to see if that fixes it, I really hope I don't have a hardware problem.
Thanks in advance

Quiet microphone in Snapchat

Hi there
When recording videos with Snapchat, the sound is way too quiet. When using other apps like voice recorder or the camera app, it works fine. I also recently replaced the battery cover
I suspect the issue is something regarding which microphone Snapchat uses. Maybe the the mic doesn't function properly without the noice cancellation mic, which Snapchat may not utilise etc.
Does anyone else have this issue? Does anyone know how to fix it?
heres some more info on the problem: snapchat only records audio with the top mic on this phone, which is probably supposed to be used for noise cancellation. this issue is not apparent in all non-sense roms, like cm10.2 and aosp based romps; the mouthpiece mic is used to record audio so the audio works fine. but then in custom roms the camera profile is different, so it is not possible to record 10 second videos in snapchat. it stop recording at about 6 seconds. heres more info on the 2nd issue: https://jira.cyanogenmod.org/browse/CYAN-2343.
Thanks

Heey .. I've the same problem with my HTC ONE X ... this is what I dislike about Android in general, each phone has its own running kinda system, yet all android apps are the same in every device despite the differences.

Unless you own a Nexus, GPe, or soon a "Silver" certified device. Something maybe to consider when purchasing my next phone

[Q] Video recording at around 15fps instead of 30 on any Non-Touchwiz roms.

This has happened with every Non-Touchwiz based roms I have flashed.
Currently using this rom: http://forum.xda-developers.com/showthread.php?t=1989907
Is there any fix for this? I'm heading away on a trip in a few weeks and I'd rather not have flash Touchwiz just to record video at 30. I've always been a fan of stock android but this is the one bug I cannot stand. I've searched on here for weeks but never found my exact problem, hence this thread.
This happens in every camera app I can find, the image preview in both photo and video mode appears to stutter and lag. Obviously in the photo mode it doesn't matter, but the video maintains this lag and low fps into the video recording. It may even appear to be lower than 15, but I haven't measured this. The front camera appears to be unaffected however.
Regardless of the video/audio codec and resolution combination I use the problem still persists.
There's also a bug where instead of stereo audio, there is only audio in the right side. But that doesn't bother me as long as there is a fix for the fps issue.
Thanks.

[Q] Camcorder one channel audio (no stereo in video recordings, top mic low volume)

Hi,
I have very annoying issue in my Samsung Galaxy Note 2.
I'm running LiquidSmooth 3.1 (4.4.4 KitKat) ROM.
Cutting to the chase, when I'm recording video (through stock app or google camera from Play store) my phone records right channel audio very well (bottom microphone). Unfortunately audio recorded by top mic (left channel; camcorder mic) is very looooow on volume.
Example: I record a video, then I upload it on my computer, starts playing it - I can hear audio in right speaker, left one seems totally quiet. When turning volume up to the max, I can hear audio in left speaker but it's still very quiet.​
I thought it's just video recording problem, but I tested it with Easy Voice Recorder Pro - when recording mono, everything is fine. When recording stereo - same issue as while recording videos.
Does anybody encountered same issue? Is it software issue, maybe whole ROM related? Or is it hardware issue?
Thanks

Well, not especially rom related, but all AOSP, CM etc. seem to have those sound issues atm. If it is important for you, consider a TW rom.

Okay, thanks for answer.
Is it happening to everyone or just some unlucky people?

It is very common issue for all users, as I said: atm=at the moment. Even phone calls can suffer from mic troubles.
One important thing: It might be solved already lately or in the next hours or days. Read in the threads

No Audio when recording video...

Just recently I have experienced a strange issue that whenever I record the video, afterward, I get no audio when I play it back.
The mic works flawlessly when I make or receive a call no there's no issue with the mic.
Here's what I've tried so far:
1. Flashing Stock ROM and the LineageOS 14.1 .
2. Changing many camera apps on playstore to record the video.
I have never used a Bluetooth headset with my phone so that also eliminates the possibility.
Can anyone figure this issue out as I am kinda confused whats wrong with this device...
Thanks!
