@viq @samueljohnson, whereas I have pipewire 1.4.2 and pulseaudio 17.0; and I see pipewire 1.4.9 in stable-backports.
Right now, it works. A while ago, programs would start up with a chance of outputting audio to one monitor instead of to headphones, but I seem to have fixed that.
Do I risk breakage by installing that newer version or do I stick with stable…
