I found an old patch to bypass /dev/dsp and OSS and applied it.
This will now have sound on Ubuntu 12/14, Debian Jessie etc.

Place the binary anywhere (i recommend /usr/local/bin)
Place the conf in ~/.snes9x

I couldn't get minizip to build on ubuntu12, so you'll need to unzip your roms
as this build doesn't have it built in.

Enjoy --wicknix
