Calls: ALSA UCM config not making a difference with volume - lightwo - 05-07-2024
Arch Linux ARM Danctnix + Phosh (GNOME/Purism Calls application).
I tried to change the volume the microphone has during calls as per two sources (1) (2):
/usr/share/alsa/ucm2/PinePhonePro/VoiceCall.conf
Code:
cset "name='ADC Capture Volume' 0"
cset "name='Mono ADC Capture Volume' 0"
cset "name='IN1 Boost' 0"However, during calls, the volume on the other end is still unbearably overblown, even after rebooting.
I disabled "headphones" and "front camera" switches if that makes a difference.
For reference, I also attempted to call under postmarketOS, and the volume wasn't overblown.
RE: Calls: ALSA UCM config not making a difference with volume - lightwo - 05-09-2024
I had the idea to wipe these directories:
Code:
~/.local/state/wireplumber
~/.config/pulse...but that made no difference, aside from volumes chosen by the user being reset. Call microphone volume remains to be extremely loud.
Among audio servers, aside from ALSA obviously, I only have PipeWire installed.

These are currently my 2 cases for a phone call.
PPP rings...
Me: Can you hear me?
Other person: Yes
Me: Do you have an echo?
Other person: Yes

This issue started on kernel 6.8 something.
It does not happen with postmarketOS because they are still on older kernel.
This line is the microphone volume control:
Code:
cset "name='ADC Capture Volume' 0"Unfortunately with newer kernels that 0 is still way too loud.
Default should be 47 (in my understanding 47 should be something like: "I will transmit your voice to modem in the exact same level as you speak". If you put that to 0 then it should transmit your voice in lower than you speak. And for example if you put it to 100 it should transmit louder than you speak)
Well how ever this currently not working like it should (not with any kernel).
Most decent callaudio volume is with kernel below 6.8 and ADC Capture Volume somewhere near 160.
Then you will have issue where incoming call to suspended PPP will decrease the mic so much that it is almost completely silence.
So you don't have good options, sorry.

Well then, I guess I shall get the keyboard (battery life not necessitating suspend) and rely on online calls/messages only, at least for the time being, or perhaps switch back to pmOS. Thanks for the input.
This thread seems to be overall more relevant, so I am making a follow-up post there.
There's just one thing though...

But I am running 6.7.7 at the moment. Does that change anything at all?

Matter of fact it might change something. I am not 100% but almost that with kernel 6.7.7 you should get almost tolerable callaudio in some cases.
try
sudo pacman -Rdd wireplumber && sudo pacman -S pipewire-media-session
reboot and try to call someone.
iirc Arch PPP image comes with wireplumber by default. There is issue with wireplumber (and callaudiod) where voicecall is not routed correctly every time and most of the time it happens in first call what you made.
Why that is issue? Because with older kernels if you did make a call and have audio routed to Speaker (instead of earpiece) your mic becomes really loud - and the mic will stay loud until you reboot. Wireplumber will start often the first call with speaker mode (this is bug) but same thing happens also if you just toggle speaker during call.
And then what? If things work okayish you need to set Capture volume to 160 or near to that. Then just don't suspend or don't use speaker mode during calls and you have tolerable callaudio.
Please also report did it work because I am not 100% about the kernel version thing

Sorry for the late response. Nope, switching to pipewire-media-session made no difference.
