Looked around and didn't see this...
I'm using MaLa on a PC that does other things besides Emu
and I noticed two things.
One, if I set the background sounds to fade in/out, when I exit MaLa it drops my "Wave" channel to zero and leaves it there, effectively muting everything else.
Two, even if the fade in/out is OFF, it still forces my "Wave" channel to 50%. I can't get it to be at 100% no matter what I do in MaLa or the Windows XP Mixer applet.
I'm guessing this has gone unnoticed because most folks are using this in a dedicated environment?
