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 bits nn 15 14 13
