This module includes intermediate storage to queue SDMA transactions prior to being synchronized and passed to the HDMI RTX Subsystem over the Audio Link. AUD2HTX works as the cpu dai in HDMI audio sound card.

Don't you need to configure the PAI as well? See [1] for downstream implementation. I'm wondering because I had to hack something similar. Without I got no HDMI audio.

While I understand this is just the DTS update, did you got any chance to send patches for the remaining bits required to have the functionality working? Am I missing something?
