Set this property to True, before adjusting ChannelCount and ChannelCountHW, if they are meant to have different values. When hardware channel count (device channel count) is different from ChannelCount a map must be provided, how different hardware channels are mapped to the the software channels. This map is implemented with the Items[i].Channel property, where the "ChannelHw" specifies the hardware channel number from which it fetches or where it stores its data. If multiple software channels point to the same hardware channel, they are summed together (audio mixer).
