After upgrading from Kubuntu 19.04 to Kubuntu 19.10 I've started having issues with only having a Dummy Output sometimes when resuming my PC from standby. I've noticed that this issue seems to occur somewhat randomly after some resumes but doesn't happen during others. Running pulseaudio -k
always fixes the issue and it never occurs on a power-up or reboot.
Running journalctl --since "1 day ago" | grep pulseaudio
after resuming my PC from standby gives the following output:
Nov 10 21:30:44 Linux-PC pulseaudio[3005]: W: [alsa-sink-ALC1150 Analog] alsa-util.c: Could not recover alsa device from SUSPENDED state, trying to restart PCM
Nov 10 21:30:44 Linux-PC pulseaudio[3005]: W: [alsa-source-ALC1150 Analog] alsa-util.c: Could not recover alsa device from SUSPENDED state, trying to restart PCM

Nov 10 21:30:44 Linux-PC pulseaudio[3005]: E: [alsa-sink-ALC1150 Analog] alsa-sink.c: Error opening PCM device front:0: No such file or directory
I do have a modification in my default.pa
config:
load-module module-echo-cancel source_name=noechosource sink_name=noechosink
set-default-source noechosource
set-default-sink noechosink
but I found the issue persisted even when the modification was disabled.
The controller that I use is the following:
00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31)
and I am using kernel 5.3.0-18-generic.
Any help would be appreciated. Thanks.
UPDATE: After discussing this issue with one of the pulseaudio devs it was found that the nvidia proprietary driver I have installed was causing this. The issue would disappear when I removed it and would come back when I reinstalled it.
After trying quite a few fixes, the solution that fixed the issue for me was running:
sudo addgroup username audio
where username is your username on your pc. After running this, I haven't been able to crash pulseaudio in about 10+ suspend/resume cycles.
