USB Sound card about android_kernel_brcm_rpi HOT 7 CLOSED

Please specify device and system version. Raspberry Pi 4? LineageOS 16, 17, 18?

I don't see anything wrong with that. Also my USB soundcard works just fine on all versions. Are you sure the issue just isn't the volume level? Go to audio settings and increase the volume to the max.

Thanks.
It is all about 18 (but situation is the same for LOs17).
I'll check but waht about mic defenitely it is not a volume issue?

from android_kernel_brcm_rpi.

AFAICT the volume level affects both input & output.

THanks again.
Earphones are done - they work (the reason was indeed vlume level). Is it possible to save it at a required level once and forever. Becuse it goes to initial level upon reboot so it is required to return back to settings and set it each and every time manually.
Mic doesnt want to work... :(
Any thoughts?

Have you tested the mic with the built-in recorder application? There been some reports that mic is not working on some third party apps on LineageOS 18.

Android resets volume levels for external audio device on reboot. You can try e.g. some Tasker-like application to automate things like this.

thanks. Of cource it is internal recorder because for the clarity of experiment nothing else is installed.

Hi, thank you once again for the support and advice. It looks like the topic can be closed since i found the solution. I've changed the mic and now it works fine. Although i still havent got an understanding on why the same mic worked perfectly well on the same USB sound card with LoS 16.
