Yeah, I was a little worried about this, but it worked fine on my Mk2 here, so I didn't bother unmuting! Mind you, I'm calling the original init at the end of my init shell script, so maybe it UNmutes it again.

Anyway, as a proof of concept it seems OK, so now we just have to make it so that it unmutes after opening /dev/dsp. Please find attached file.
Actually it would be better if it restored the original flags, but I can't be bothered right now.

I guess we could put a hack into empeg_mixer.c so that it always mutes the device before changing the EQ. But that wouldn't sound nice if you adjust the EQ while music is playing.
