(the following is from the armlinux CVS)
WaveArtist mixer and volume levels can be accessed via these commands:
nn30 read registers nn, where nn = 00 - 09 for mixer settings
0a - 13 for channel volumes
mm31 write the volume setting in pairs, where mm = (nn - 10) / 2
rr32 write the mixer settings in pairs, where rr = nn/2
xx33 reset all settings to default
0y34 select mono source, y=0 = left, y=1 = right
