I have a Radeon 4670 (Sapphire branded) connected to a Yamaha RX-V773. I am running the sound/for-next kernel (82755ab) with your "missing PCM SAD" patch applied.
The new kernel has allowed ALSA to recognise the card as multichannel and
I
can issue the following speaker-test command but I still only hear "Front Left" and "Front Right" and the Yahama seems to report the signal as
stereo.
# speaker-test -Dhdmi:CARD=HDMI,DEV=0 -c6 -t wav
Why do you use -c6 when your HDMI codec only support stereo
Node 0x02 [Audio Output] wcaps 0x201: Stereo Digital Converter: stream=1, channel=0 Node 0x03 [Pin Complex] wcaps 0x400381: Stereo Digital
All ATI/AMD HDMI codecs report stereo only here, their multichannel support is non-standard (probably predates the HDA spec).
