The aplay -L list indicated that the HDMI was ATI, likely on your 
graphics card, and that's what you want to ignore, correct?

If you're running the proprietary driver I've no idea, but with the radeon 
driver on a Turks card here (Radeon hd6670 IIRC, the logs say turks), 
kernel built-in not modular, the following kernel commandline option 
disables HDMI audio here:

radeon.audio=0

But while I know it's disabled (at least back when the kernel radeon 
driver first enabled hdmi audio by default I couldn't boot without it 
disabled, so it definitely disables it or I'd have no graphics!), alsa 
still shows it as a sound card that I can choose, I just never do, so I 
don't know what would happen if I did.

And of course I don't do proprietary so haven't the foggiest how the 
proprietary driver works in that regard.
