[v7.8.1] Pipewire doesn't detect default audio output.

Heyo, thanks for the sick app, been using it for a while.

I've been playing around with the Pipewire backend on the Tauon Flatpak (I'm running Fedora Kinoite, so all packages should be updated). Basically, upon launching and attempting to play a song, no sound comes out. This was unusual as flatpak's logs showed that Pipewire was initiated successfully. Then, upon switching the audio device from Default to [My headphones], there was audio output. Switched it to my laptop's speakers and there was output there as well. So, detection of default output device is broken somewhere (works fine on the PulseAudio backend).

Not a deal-breaker, it's experimental after all, just wanted to give a heads up. Can someone check on their machine to see if they experience the same issue?
