Any tips to improve the audio quality of calls on the PinePhone Pro?
#1
Hi!
Phone calls work on my PinePhone Pro with Manjaro ARM Phosh Beta 30, but the audio quality is problematic for others (too quiet and/or noisy).
I tried with the (nearly) free custom firmware for Pinephone’s modem and editing the file /usr/share/alsa/ucm2/PinePhonePro/VoiceCall.conf . Currently I changed the line:

Code:
cset "name='ADC Capture Volume' 47"

and line:

Code:
cset "name='Mono ADC Capture Volume' 47"

With a value of 84 it seems that the audio quality is better, but it gets worse again after a suspend.
If I install pipewire, the audio gets too noisy.
The problem also remains with other distributions.
Any idea?
Thanks!

Currently there is no fix - expect to change ADC Capture values.
But read the thread tookmeayear linked above.
megi is working on this and maybe we get working callaudio sooner or later Smile
