I've ran some very simple audio playback tests, here are my results:
* alsa - works
* pa - works
* oss - works, but it looks like I have to specify both in.dev and 
out.dev if the default /dev/dsp does not exist, otherwise I just get a 
generic "Could not init `oss' audio driver".  We need a better error 
message here IMHO.
* sdl - works
* spice - yes, it's broken now, I'll fix it in the next update.  I've 
also found a second bug (SIGSEGV if the guest starts playing while no 
client is connected).

No idea, I don't have a windows or mac computer.  I could try it in a 
windows VM though, if I figure out how to compile qemu on windows.
