This kinda stems from this issue I asked about a while back, Pipewire an PulseAudio have caused me quite a bit of confusion lately as I recently started experiencing crackling/static sounds from my Bluetooth speaker when playing audio.
After days of digging and thinking that I’ve fixed the issue by editing /usr/share/piperwire.conf and /usr/share/pipewire-pulse.conf and following guides like this one (I know the link is for EndeavorOS) I have seem to come to the conclusion that Pipewire-ALSA is the issue to the crackling/static sounds I’m hearing.
I stumbled upon qpwgraph which appears to visualize the flow and when I disconnect Pipewire-ALSA from the flow the cracking sounds stop, now from my understanding Pipewire and PulseAudio cannot coexist which is causing my confusion because Pipewire-ALSA also appears to connect to a bunch of PulseAudio Volume Controllers.
Pipewire-pulse provides compatibility to programs that may not directly support pipewire yet.
Pipewire was developed to be a total drop in replacement to the Pulse audio sound server. It has compatibility layers that allow other things to talk to it.
Edit: debian is not showing pipewire-alsa as a hard dependency of pipewire https://packages.debian.org/trixie/pipewire
