@ambitiousslab @urheber > either one side canβt hear the other, or the audio quality is too quiet, or not very good
Which OS are you using? I haven't had call audio issues for ages on PureOS (I'm not a heavy caller though π)
I'm running postmarketOS v24.06. I could easily have messed something up though!
@ambitiousslab It's probably PipeWire. AFAIK nobody adjusted the audio pipeline to work there with echo cancellation and noise reduction yet. I wouldn't consider it suitable for phone use until that happens. It's not rocket science, PipeWire is actually more flexible than PulseAudio for this kind of stuff, but... someone has to do it. Switching back to PulseAudio and reproducing the config from PureOS (including ALSA UCM profiles) would likely give you much better experience right now.
@ambitiousslab (I have to admit that it's partially my own fault; I have reworked L5 UCM profiles from the ground up long time ago, but neglected upstreaming them and now there are flawed profiles in upstream repos βΉοΈ)
Thanks for explaining some of the history, it makes some sense and gives me some things to try. Thanks for all the work you've done on the mobile stack as well. It's made my life a lot better. And maybe one day I'll be able to ditch the backup nokia too :)
