Hi!

I've tested pipewire as the main audio server on my machine (HP Elitebook 840 G6). SOF drivers work fine with pulseaudio. After starting wireplumber sinks get properly registered and qjackctl shows that audio from firefox gets routed to my sound card. Unfortunately my speakers remain quiet and the system logs shows:

Any hints how to debug it?
