Nor do I want to reboot it to do music stuff; I'd only do that for only an hour here and there rarely, and wouldn't want to lose my environment (read: emacs session, mosh sessions, and Firefox/Chrome tabs) and bring it all back.

I was able to get audio working in Kvm using spice instead of vnc.
Basically you should set up "spice" in display-vnc reachable from the
guest details in VMM.
I've never experimented using it in real time i've just loaded some old
projects i did with reaper years ago and it did work (ignoring the
latency while recording of course).
Hope it helps
