How SKAA Volume Works
hVOL is “Global” volume which
mirrors the host device volume
whenever possible. It is maintained
and stored in the SKAA transmitter.
bVTR is “Local” volume
which is stored in the SKAA
Receiver. The +/- volume
buttons always affect bVTR.
nVOL is transformed through a volume table
(customizable) residing inside the Ginseng and
the resulting value is sent out to the DAC via
I2C as a hardware volume control command
