/*
* C-Media 9739 part is weird. Instead of having independent volume
* controls for each of the channels, it uses a single master volume
* and just provides mute support for the other bits. It does this
* for PCM volume as well, so we can't use it either. Ugh. It also
* has an optional 30 dB mic boost. Apparently the 9761 behaves in
* much the same fashion as the 9739.
*
* C-Media 9738 is a more or less typical 4CH device according to the
* datasheet. It however supports jack retasking allowing the line in
* jack to function as a surround output. Google suggests that the
* volume controls on this part are about as busted as on the other
* parts. So, we just use synthetic volume for it.
*
* C-Media 9780 is largely a mystery (ENODATASHEET).
