Subdevice #0: subdevice #0

so, i have an ALC662 chip. But i cant see a HDMI-Audio Device. The GFX Card is an Intel GM 965 and works fine with HDMI-Video ( debian 11 ). On Windows 7, all things working fine. HDMI-Audio and HDMI-Video.
I posted also-info, here:

I googled my device and found it here: ( its an old device ).

This is a shot in the dark.

Open 'pavucontrol' (install it necessary) and check the Output tab. There should be a drop-down menu and you can see if your HDMI is listed there. You can also flip through the other tabs to see if something else is amiss.

You should probably edit your first post to include that nugget of information.
