Currently, the "ao" use flag is masked for the package games-emulation/zsnes. Since the current stable version of app-emulation/emul-linux-x86-soundlibs provides libao, I believe the mask can be dropped. I did that manually on my system via package.use.unmask and zsnes works fine here. Furthermore, making zsnes use libao makes it play nice with pulseaudio.
