I only run PA and dbus for OBS Studio. One day this system will be back to vanilla ALSA with apulse to fill in any gaps. :)
I'm glad you were able to find a solution. Audio is one of those things that's almost unique to every system and problems in one system (even with the same hardware) may not match the other, so I chose to give you a handful of options to try, since it's not always clear which solution is best. If you ever get sick of manually updating the card numbers, you could probably write a script for it.
