Supports 8-bit linear and 8-bit muLaw samples
Output: digital, 16 bit, 4 channels
Output sample rate is the input clock / (288 * 2).
superctr: The clock divider appears to be configurable for each system.
Below is a list of the divider values followed by the systems that use it.
* 228: System 11.
* 288: System 22, Super 22, NB-1/2, ND-1, FL.
* 296: System 23, Super 23.
* 332: System 12.
