I run speaker-test -D hw:1,3 -c 8 Now it actually worked a bit. The speaker-test runs as it should, but everytime it tries output to "none-two-channel" channel (LFE, Rear Left, Rear Right.. etc), it doesn't output anything. And I can see on the receiver that the (2 channel PCM stream, but should say 7.1 Multichannel) is lost every time except for Front Left/Right channel.
Then some information is missing. ATI seems to have implemented LPCM in a vendor-specific way.

It recognizes when I take the cable in and out, or toggles display output (0xffffffff when connected).
OK, it's good to know. It means that the pin-sense reports only the pin-detection but nothing else unlike other codecs. So, it's basically bad to use generic HDMI parser for this codec.
And, when you wrote "I still can't run speaker-test with more than 2 channels", do you mean that you got an error? How did you run? With the patch, the driver should take up to 8 channels. If not, something was wrong -- either the patch wrongly applied or the patch wasn't enough.
