No sound

I booted up a game last night was incredibly fested with lag so i muted the ps3 emulator in my volume control now whenever I load another game it no longer gives sound and yes just so no one asks i have it unmuted in my volume control now.  I've done a restart checked my audio is on default settings I don't know what else to do here.

Can anyone help?

Missing log file

Make sure audio on emulator is not muted (check per game configuration if you are using it)
