/**
 * Implementation of custom interface class for play functionality created by the 
 * CMMFSwCodecWrapper::CustomInterface() method.  It provides 
 * access to miscellaneous functionality such as volume settings
 * Ports of sw codec wrapper may do this differently eg via EAP
 * note don't use RMdaDevSound::TCurrentSoundFormatBuf so send
 * across the sample rate and channels because 1)it would mean
 * mmfswcodecwrapper.h would have to include mdasound.h and 2)
 * the buffer size and encoding members are not required 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.)
