@prototype

Custom interface class for play functionality created by the
CMMFSwCodecWrapper::CustomInterface() method. It provides
access to miscellaneous functionality such as volume settings.
Ports of the sw codec wrapper may do this differently eg. via EAP.
Note Users should not use RMdaDevSound::TCurrentSoundFormatBuf to send
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).
