sprintf(jack_name, "HDMI/DP, Pin=%d Jack", pin->nid);Such a name makes sense only to be compatible for PA, and then this string isn't compatible. Note that it's not about pin but for PCM stream. You may wonder why it matters -- see the whole discussion on MST support.
So in our case we have added only one PCM Backend in DSP. In codec we have one DAI supported, thus creating a DAIlink
The Codec DAI is mapped to a stream which we fix to a CVT. Future we will add two more streams which are mapped to other two CVTs.
We use MUX controls to allow user to specfiy how CVT and PINs are connected togther, this way we can route stream to any pin.
Extending this concept, behind a pin for MST there may be different 'ports', right? Shouldn't that be another mux configuration :) So we can treat three streams coming to codec to be routed to any pin and then any port. Since we have only 3 CVTs we will have only 3 streams...
Back on present :), what do you recommend for us for jack name.
Thanks
