This SWI is used to read the volume settings of a specific mixer channel.
R0 can either be a pointer to a null/control-terminated audio controller device ID string (as returned by Sound_EnumerateControllers or 0 (NULL) to refer to the mixer for the current default controller.
Gain is specified in units of 1/16dB, so for example -16 corresponds to -1dB.
