Subject: AUDIO: Miles Audio AdLib: set default volume 0x7F

set default volume of every midi channel to 0x7F right on startup
fixes Amazon Guardians of Eden logo jingle music
those values were actually sent to the driver right on startup
default value for panning was 0x40, this was adjusted as well
