The codec proc output there shows that only one pin is enabled for HDMI/DP output, and that's the reason why the driver created only one stream. It's basically a BIOS setup.
The patch below should enable all pins forcibly and this should give more streams. Give it a try.

This somewhat improved the situation. I get multiple HDMI devices on the card now, and the default seems to be the actual HDMI port (as opposed to the DisplayPort).
But I can't manually control where the audio goes, and at one point (I think when the TV was off), it automatically switched to the DisplayPort.
The connection is indeed managed dynamically, hence you cannot expect which port is for what exactly. The actual connection should be checked by EDID (or ELD).
So, does the sound output from DP also work as expected, as well as HDMI?
