[alsa-devel] HDMI LPCM (7.1) with AMD/FGLRX

[Andrée 'Glaucous']

Okay, after waking up and stopped being stupid, I cloned latest alsa-kernel,
this however still resulted in your patch failing, but I
managed to install it manually.

I still can't run speaker-test with more than 2 channels.
(HDMI is card1 now)

Now monitor is present (which I should add, it also was when I updated to
kernel 3.0 without any alsa patch), and there are many more channels,
which is probably because due to your patch hardcoding the channel count.
