ATI/AMD codecs do not support all the standard HDA HDMI/DP functions, instead various vendor-specific verbs are provided.
I've just tried my HD6970M (BARTS, DCE5) in my Samsung NP700G7A-S01PL.

Command: speaker-test -D hdmi:CARD=Generic,DEV=0 -c8 -r192000 -F S16_LE works, I just have 5.1 (not 7.1), so Side left goes to the Read left and Side right goes to the Rear right. But they were working!
Next I've used howto from http://phoronix.com/forums/showthread.php?27348-TrueHD-DTS-HD-E-AC3-Over-HDM... to test DTS MA and TrueHD.
In the file from howto I've used: card Generic and then tested:
zajec@linux-samsung700g7a:~> aplay -D hdmihdtest0 -c8 -fs16_le -r192000 thd.spdif Playing raw data 'thd.spdif' : Signed 16 bit Little Endian, Rate 192000 Hz, Channels 8 zajec@linux-samsung700g7a:~> aplay -D hdmihdtest0 -c8 -fs16_le -r192000 dts.spdif Playing raw data 'dts.spdif' : Signed 16 bit Little Endian, Rate 192000 Hz, Channels 8
Hooray! I got DOLBY HD and DTS-HD MA on my Denon 1912 display!
Now the main question... do you have any experience on using DTS-HD MA (or TrueHD) with mplayer? :|
