I'm using HDMI output on an HD 2600, using KMS from kernel 2.6.37:
The problem is that only 2ch are supported (not 1, not 3 or more). I
tested with speaker-test, it only works with -c 2.

So how can I access the other PCM channels ? There are 8 of them
available in the HDMI standard, I thought the card should be able to
drive all of them.
