This would be incompatible with the "First" foundation. If we'd had a "no regressions" rule for pre-PA audio, we'd probably never have landed PA, or not for years. Are things on the whole better since we did? I'd say yes. Will our first release with pipewire probably have some bugs that constitute regressions from the previous audio setup? Almost certainly. Especially given the sheer amounts of stuff people do - see your config below - I think we'd find it difficult to have a "no regressions" rule and still be Fedora. Part of Fedora's job is to adopt new things and shake some of the initial bugs out of them. > Of course we would need to start with collecting the use cases, and > this will be different for every user.

I bet not. Would we have as capable a PA today if Fedora hadn't taken the leap to include PA?

It would be good to cover at least a range of commonly used configurations here. QA folks, this is definitely a Change that (if approved) we should do a Test Day (or several) for, and probably one that could use help with a better test plan. Do we have any domain experts who'd like to volunteer to work on that?
