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.
