Sorry, didn't change anything.
I doubt that the problem is wrong default settings of alsa.
I run pulseaudio -vvv and the output was interesting:
Pci0000:00/0000:00:08.1/0000:07:00.1/sound/card0
and
pci0000:00/0000:00:08.1/0000:07:00.6/sound/card1
Where the latter one is the one that is not used by pulseaudio.
Both report "UCM available for card HD-Audio Generic"
Note: the card name "HD-Audio Generic" is identical, and this is reported by
alsa-libs, as far as I could see from the code.
Then it finds HDMI1-3 for both cards.

Alsa-info.sh reveals further info:
!!Soundcards recognised by ALSA

0 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfd3c8000 irq 91
1 [Generic_1 ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfd3c0000 irq 92
2 [acp ]: acp - acp

To me it looks like as if pulseaudio is quering card0, getting the name "HD-
Audio Generic", finding the HDMI channels; then it tries to read card1, gets
also "HD-Audio Generic" as name and hence the same channels as for card0.
I have no idea how to fix this.
