AXPBRMTMIX specifies the mixing parameter for the controller's speaker. Volume is expressed as a 16-bit, fixed-point number (most significant bit for the integer, 15 bits of fraction).
Note: The DSP does not clamp volume-ramp computations. Your audio application is responsible for ensuring that the computation remains within bounds.
Mixing parameters are set for each voice.
When playing audio from a controller speaker, not only must the appropriate mixing parameters be set, but voice processing for the controller speaker must be enabled by setting AX_PB_REMOTE_ON. Furthermore, the value of axvpb.pb.rmtMixerCtrl must be initialized correctly in order to apply mixing parameters.
The user must assert the AX_SYNC_USER_RMTMIX bit in the axvpb.sync member when any of the above mixing parameters have changed.
Note: An Aux bus for the controller speaker is not implemented.
