The audio will still work, but during the game you will encounter pauses when the emulator has to decode the audio before playing it. The bigger the audio file (and the slower your CPU is), the longer the pause. If the audio is already decoded in the tmp folder then the emulator just plays the decoded audio directly so no pauses will occur. Therefore for best performance just leave the tmp folder alone and get a larger hard disk drive instead.
