39  * C-Media 9739 part is weird.  Instead of having independent volume
40  * controls for each of the channels, it uses a single master volume
41  * and just provides mute support for the other bits.  It does this
42  * for PCM volume as well, so we can't use it either.  Ugh.  It also
43  * has an optional 30 dB mic boost.  Apparently the 9761 behaves in
44  * much the same fashion as the 9739.
45  *
46  * C-Media 9738 is a more or less typical 4CH device according to the
47  * datasheet.  It however supports jack retasking allowing the line in
48  * jack to function as a surround output.  Google suggests that the
49  * volume controls on this part are about as busted as on the other
50  * parts.  So, we just use synthetic volume for it.
51  *
52  * C-Media 9780 is largely a mystery (ENODATASHEET).
