We recently checked the behavior on Windows and it always switches the audio to HDMI no matter what (even with headphones connected), so that tends to be the expectation from OEMs. We may change our mind at some point, but for now we are sticking with that policy downstream. Ideally all the changes we are making to support this case will be generic enough that they make sense upstream as well and we only have a small downstream patch set changing the ports / profiles priorities. As you mentioned, when this code runs the decision to switch the card profile to HDMI has already been made. But on setups where one card has the analog ports and another card has only HDMI ports, the HDMI card will always switch to a HDMI profile when HDMI is connected, and (unless I'm missing something) the streams will be moved over to the HDMI sink. Let me know if the above comment makes sense, and if you still want to have this patch upstream, in which case I can re-send it as a MR.
