Hi, I was redirected here by pulseaudio maintainers for an issue I thought was at that layer : https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1344
After a fresh reboot, arecord / parecord work fine, and the level meters in pavucontrol react normally. If I start audacity, the card gets in a state where the level meters become sluggish, and recording either drops 90% of samples, or records approximately 10x too fast. Playback is always ok, unaffected.
I cannot fix that state other than by a reboot. The obvious "closing audacity", restarting the pulseaudio daemon, have no effect. Tried kernels 5.15.24 and a recent 5.17; same problem.
I posted some detailed debugging info on that pulseaudio issue tracker, as well as pastebinned alsa-info.sh output here: http://alsa-project.org/db/?f=7ee784003379252acfef25de5fecbdfd559fe342
The problematic hardware is Card 1, Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) HD Audio Controller [1022:1457].
Test command : pasuspender -- arecord -D hw:1,0 -f S16_LE -c 2 -r 44100 arec_pasusp.wav
Here's an example recording of me saying 'test' : https://gitlab.freedesktop.org/pulseaudio/pulseaudio/uploads/5a51081fcd55ecd...
I have no ~/.asoundrc or related files.
Anything I can try to narrow down the cause of this ?
Thanks! Chris
