Personally, I think it is an incompatibility between the ancient
lib32asound2-plugins from stable and the (probably more up-to-date) rest of 
the sound system from testing. There's also the small matter of zsnes spamming 
"ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred" as soon as I open it 
and - when I attempt to quit - going into an infinite busy-loop.
