Note that the eight PCM channels of a K054539 do not have separate
volume controls. Considering the global attenuation equation may not
be entirely accurate, k054539_set_gain() provides means to control
channel gain. It can be called anywhere but preferrably from
DRIVER_INIT().
Parameters:
chip : 0 / 1
channel : 0 - 7
gain : 0.0=silent, 1.0=no gain, 2.0=twice as loud, etc.
