<ratio> = 00, 01-FD, FE-FF (hex, one byte)
When = Mixer 1 or Mixer 2, specifies the audio ratio or reports the current ratio on a reply.
00 =Audio ratio NOP
01-FD = Audio ratio linearly corresponding to -18.0 dB through +18.0 dB. Mixer ratios change in 0.375
(3/8) dB steps.
FE-FF = Audio ratio corresponding to +INF dB.
<bal> = 00, 01-FF (hex, one byte)
On a stereo channel, specifies the audio balance or reports the current balance on a reply.
00 =Audio balance NOP
01-FF = Audio balance linearly corresponding to 10.0 dB Left through 10.0 dB Right. Balance changes in 0.375
(3/8) dB steps.
<gain> = 00, 01-FF (hex, one byte)
Specifies the audio gain or reports the current audio gain on a reply.
00 =Audio gain NOP
