Agreed. The latest Debian upgrade installed pipewire for me, and I didn't even notice, everything just worked fine! And that after years and years of fiddling with alsa and pulseaudio configs, uninstalling pulseaudio, hacks upon hacks to get stuff working with either, etc.
Debian 11 doesn't make pipewire replace pulseaudio, alsa or jack.
Should have mentioned, I'm running testing/unstable. After the stable release, all the new experimental stuff for the next release floods into unstable.
oh, how exciting! time for a dist-upgrade tonight then!! :-)
