Static sound when no sound is played

Hello everyone!

When I stop playing any sound (music, video calls, games) after a few seconds (~30 seconds) a static sound starts sounding and it is really loud but just when I stop playing any sound.

I just have simple speakers connected to AUX of my PC, I've already updated it and reboot it but no solution.

Any help is really appreciated!

Has it always been like this since the installation?
Only later?
With headphones too?
M$ 10/11 shut down properly?


Thanks for the reply!

It has not being always like this, it happened after an update some days ago.

With headphones happens also, the sound it is not that loud on them but a loud click can be heard after a few seconds of stoping any sound.

Shut down multiple times properly.

Check what change some days ago.
Check sound settings.
Try other kernel.
Search the web.
Check log files at the time you stop the sound file, …


This could be HW related.. check your cables, and connections.

AUX outputs that came via cable to the top of the PC case are prone to picking up noise. Again, it depends on a lot of underlying factors. The source of distortion can be both common mode and EMI. In the PC case it could EMI because there are devices that can radiate EMF

Audio issues can come from noisy ground or ungrounded power outlets as well.

Some things to keep in mind.


Try disabling node suspension as described here: PipeWire - ArchWiki

With wireplumber, create a new file to overwrite the default configuration:

(or /etc/wireplumber/main.lua.d/51-disable-suspension.lua)
table.insert (alsa_monitor.rules, {
  matches = {
      -- Matches all sources.
      { "", "matches", "alsa_input.*" },
      -- Matches all sinks.
      { "", "matches", "alsa_output.*" },
  apply_properties = {
    ["session.suspend-timeout-seconds"] = 0,  -- 0 disables suspend

Trying a different kernel did it 6.4.5-1-cachyos-bore
