PipeWire - No output devices

Hi, I am new to Linux and currently trying to set up my sound system. My sound server is PipeWire, my session manager is WirePlumber, and I use PulseAudio clients. Everything seems to be up and running:

$ pactl info
Server String: /run/user/1000/pulse/native

However, as you can see from `pactl info` output, the default sink is auto_null. Also `pactl list sinks` doesn't list my headphones plugged in the audio jack port. With pavucontrol, only dummy output appears in the output devices.

I have read several topics, but can't seem to find an answer to my issue.

Best,

Frederic

Re: PipeWire - No output devices

Please edit your post and use [ code ] tags (not quote tags) when posting output. This makes the output easier to read and provides a scroll box for long output.

How to post. A sincere effort to use modest and proper language and grammar is a sign of respect toward the community.

Re: PipeWire - No output devices
