Yeah I did that for a while with firefox.

And then firefox broke apulse again due some sandboxing permissions, and you had to override it with some about:config flag: security.sandbox.content.write_path_whitelist

So that worked for a while and then the audio in some proton games stopped working, and that’s when I said fuck it and gave up. I’m only prepared to play the whack-a-mole game for so long, and if the solution to pulseaudio flakiness becomes even more alsa related flakiness, it’s not worth it anymore.
