Did you try other Kernel?
My inxi with zen.

  Sound Server-2: JACK v: 1.9.21 running: no
  Sound Server-3: PulseAudio v: 16.1 running: yes
  Sound Server-4: PipeWire v: 0.3.57 running: yes

PulseAudio is on. Just a idea, but I am not a specialist for sound.


I was on the zen kernel originally, but I switched to lts because of my usb wifi adapter that needed a compatible driver.

Maybe I should just activate PulseAudio? What would be the systemctl command for that?

Yesterday also I had a problem with Bluetooth and my bluetooth headphones

I use the Bluetooth configurator integrated into KDE (Plasma).
I deleted the configuration related to the headphones and I created a new one.
Headphones started to work again.


If you feel that this is the problem, just install pipewire-pulse

In my experience the A2DP protocol is not working at all. Some profiles played back my microphone input into my headphones, and some just do not work at all, like the afore mentioned A2DP. For me apt-x and apt-x-LL worked best, or rather at all. Are these not available to you?


I don't see those profiles. I attached a screenshot of the ones I see

@LorenzoHex how did you delete the config?

Do you have libreeaptx installed?

Edit: Obviously you have, it's a dependency for pipewire.

But: Does your dongle support it? I read about some trouble with different dongles not supporting it

Regarding the config deletion: see /usr/share/pipewire - You might get away with just deleting those files and reinstalling pipewire to restore them

I got it figured out. There are three places in pavucontrol where you have to make the right choice, and it needs to be done manally.
1 Playback
2 Output devices
3 Configuration

After choosing the right devices and profiles in all three places, sound works as expected. :grinning:

I just got a several updates that were audio-related, so I don't know, maybe that helped. But probably, I just missed the right setting in one of the above-mentioned places.
