I’ve been using Pipewire for a while, it was great because I could use my Bluetooth headset with a better audio Codec than in Pulseaudio. Unfortunately, my headset stopped working one day suddenly with Pipewire. (maybe after a dist-upgrade?) No amount of disconnecting, unbonding etc. would work. Went back to Pulseaudio as a sound server. Sad.

Neither Pulseaudio nor Pipewire remember to use by screen speakers (hdmi) as default, though. It always switches back to the internal sound card.
