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-HDMI-On-Linux
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? :|
