When the DVD Navigator filter goes into karaoke mode, it informs the audio decoder through the AM_PROPERTY_DVDKARAOKE_ENABLE property. The decoder should then mute audio channels 2 through 5 until it receives from the DVD Navigator an AM_PROPERTY_DVDKARAOKE_DATA property with a pointer to an AM_DvdKaraokeData data structure indicating how the auxiliary channels are to be mixed.
