+across the sample rate and channels because 1) it would mean
+MmfBtSwCodecWrapper.h would have to include mdasound.h 2)
+the buffer size and encoding members are not required and 3) 3rd party ports
+may not use RMdaDevSound.
+
+Note also that this interface is just a simple interface to get
+and set values. No checking is perfomed on the values sent (hence the
+Set methods do not return an error code).
