NOTE: There is only one audio volume setting per output on any specific plane.
The audio volume is shared by the left and right audio outputs. The audio volume
is stored in non-volatile memory. When power is removed and restored, the audio
volume settings are retained.
If the audio is set to “follow-all,” upon initial selection (step
2) the I/O plane and
associated input and output buttons light amber. When an input or output button is
held for 2 seconds (step
3), the I/O plane button flashes red.
