Each DMA channel can be mapped to a stream in HDA. Each stream is mapped uniquely with a stream tag. The stream is programmed in both host and codec. In host the DMA is programmed with this stream tag and based on this DMA picks data from host buffer and puts it onto the link. Similarly the codec converter is programmed with the same stream tag and codec receives packet from the link associated with the stream tag.
Are these arbatrary tags? If so why not just pick tags that look like normal TDM timeslots?
If I understand correctly, the tag will be programmed in the tx_mask and all other arguments will not be used.
