In which I'm a goober and don't clean up after
myself and accientally don't fix the issue I tried
to fix in my last round restart PR.
The audio is now maintained just like music during
restarts (yippee to ContentAudioSystem::OnRoundRestart)
This needs a refactor but at least the defect is fixed now.
