Audio hangs with pipewire

[bowlofeggs]

I'm using Bottles via Flatpak on Gentoo Linux, with audio provided by pipewire. I've been using the "gaming" profile to launch Bloons TD 6 with the Epic store. At some point during play, typically 5-20 minutes in, the audio will stop playing.

Interestingly, when this happens, audio will also stop playing for other applications, which makes me wonder if this might actually be a bug in pipewire itself: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4343

In any case, I was wondering if anyone knew of any tunables that might be interesting to try in either Bottles or Wine.

To close the loop on this, I did find that setting the env var PULSE_LATENCY_MSEC seems to solve the issue, at least for this one game. I think I ended up setting it to 100 or so.
