Looks like this was a long time ago. I was using pulse audio on Ubuntu. Which I guess is ancient now. I had to edit /etc/pulse/default.pa And edit things like load-module module-switch-on-connect which dealt with USB connect event handling.

I don't use bazzite, looks like that is a fedora based distro. Which I guess now uses pipewire/wireplumber. (And I guess ubuntu does too now?)

I would suggest googling something like "pipewire session.suspend-timeout-seconds"

You'll find a bunch of similar issues:

This is for Mint, but I'm thinking this same "session.suspend-timeout-seconds" property is going to be what you are looking for.

It looks like setting that property to 0 might prevent suspend from stopping your audio.

If not, I think this gives you a pretty good idea of where to look for the config files:
/usr/share/wireplumber

And from there, you can probably get a good idea of the various property names and what they do.
