Speakers and gerenally all devices connected to my sound card (not the Bluetooth ones) are getting disable some time after booting

Not sure if it's a hardware problem, but this didn't used to happen in the past (it happens since November). To re-active them I have to change the output from the settings, but again if no sound is played, the speaker and the microphone are getting disabled...

The problem smacks of "power saving" features. The solution will most likely involve the same.


Hahaha I'm so dump for all those months I thought it was something with my sound card, thank you!

No wait, it still happens..

You have two items that you might want to start with:

You have both PulseAudio and PipeWire running, you might want to remove one. ALSA uses one of the other two, and can be left alone. Currently, Garuda uses PipeWire, but the choice is yours to make on which one to keep.

The current bios is 2604. While the updates don't mention sound, manufacturers can be lazy and state "System stability" if it not CPU or Network.

Now, if there is still no progress, this link is for buzzing sound, but has how to disable power settings for snd_hda_intel driver.

Hope something helps here for you!


So first I'll try removing pulseaudio
It's safe right?

Just make sure that pipewire-pulse is installed, which covers that "gap" (but this is provided by default via the pipewire-support package, so...)


I can't install pipewire-pulse or pipewire-support, because it says it breaks some pulseaudio dependecies

It's supposed to. Be brave, replace them.


I don't wanna risk my OS, I had lots of trouble in the past

PS: Go ahead and take a manual snapshot.... WAIT...

Snapper :ninja: :ninja: :ninja: to the rescue!

(1/1) Performing snapper pre snapshots for the following configurations...

( 9/10) Performing snapper post snapshots for the following configurations...

snapper should be triggered by pacman to make pre and post snapshots. You're good @RaptaG

Just FYI, Snapshots by default don't include user configuration files in the user's home directory. If you want a backup of those conf files in home, you need to configure that yourself.
