Temporary Sound Problems

Support Audio
1

Hi,

when I wake up my PC after stand-by, I have a slight sound problem. The issue is that there is a short increase in loudness. It is as if someone turned up the volume by 80% or so for a fraction of a second. It isn’t regularly, but around every 30s or so.

When I plug-in my headset on the front connector the issue is gone. Also after unplugging the issue is gone at first, but after some time it reoccurs.

So very strange after all.
Any clues how to debug this?
Or maybe some command to “reset” sound?

PulseAudio can be reset to default settings by deleting contents of user configuration folder

rm ~/.config/pulse/*

and reboot system or restart pulseaudio.service

systemctl --user restart pulseaudio

If that does not work to resolve issue with change in volume, check pulseaudio.service for errors

systemctl -l --user status pulseaudio.service

I have identified the problem.

It was the front audio module (with headphones and mic jack) on my pc case Once, I unplugged the audio header from my mainboard, the problems have stopped.

I guess the module is faulty and/or of bad quality.

PS:
Thanks @nikgnomic, I tried your suggestions but they didn’t work (for obvious reasons in hindsight).
