SteamOS (Pipewire) has no sound

The SteamOS 3.7.x rollout has caused AppImage users to suddenly have no sound. Upon investigation, it would appear that the AppImage is spawning an alsoft JACK process that does not make common (implied) connections to the user's audio sink. A workaround for this is to recommend grabbing qpwgraph from the Discover store and having the users make these connections themselves:

steamos-appimage alsoft channel_1 and channel_2 should route to Built-in Audio Analog Stereo playback_FL and playback_FR respectively. Patchbay -> Save and Patchbay -> Activate makes this persistent.

Since we know the tarball works, I decided to compare the audio process. It would appear that it spawns a generic openmw.x86_64 "Playback Stream" (is this a PulseAudio process?). The implied connections are automatically applied in this case. steamos-tarball

I don't think alsoft being a JACK process should cause issues, but it is a notable difference. I'm not sure what to suggest other than possibly looking into certain dependencies?
