Audio hissing while nothing is playing

Hi I installed garuda last night and today I realized, that the speakers emit a slight hissing noise. Checked back in Windows they don't. I previously had pop_os and it didn't hiss either, so I'm guessing it's some wierd configuration / driver issue (mainline arch did not hiss as well)

This means the audio chip is active.


Well yeah, but it is really annoying. Is there any way to improve on this ?

Hi there!

Hope this helps.


Try muting your microphone.


Tanks for the replies. Muting the mic sadly doesn't help :frowning:

There are a lot of different potential solutions for this. Sometimes this is very difficult to solve. I would suggest searching the Arch Wiki for "pulseaudio troubleshooting".


Did you try updating BIOS?
When did you last updated it?


You can try enabling power saving. However, this may result in "pop" noises when playback starts and stops.
