 /**

  * 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.)

  * @released
