Nope.

Yep.

"PipeWire make media worky" would work great! :D jk
Real-time multimedia capturing, processing and playback or low-latency,
graph-based audio and video processing engine or something like that.

Yep, we have similiar use cases in rde and configuration mentioned
earlier serves them quite well. According to Alsa: I don't have deep
knowledge in this area too, but according to my knowledge pipewire can
be loaded as a shared library and injected into alsa user-facing API to
process requests, so maybe a backend for ALSA-based applications or
middleend for ALSA will be more apropriate name for the pipewire role
here :)
Anyway, without the config above alsamixer doesn't work on my system,
probably with some configuration it's possible to make it work, but
bypassing pipewire, however I think it would be nice to go full
pipewire.
