2013/10/1 Anssi Hannula anssi.hannula@iki.fi: 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!
Good :)
BTW, there is a newer version (which was actually applied) of this patchset in alsa-devel@, seems you were missing from CC on that one.
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
For the record, the "howto" is mostly a workaround for missing DEV=[1..3] on (now) very old systems, instead of messing around with asoundrc you can just use "-D hdmi:CARD=Generic,DEV=0,AES0=6" instead of -DhdmihdtestX. (in AES0 the 0x2 is non-PCM flag, 0x4 is non-copyright flag IIRC - ALSA default is 0x4).
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? :|
Nope (well, any that I still remember). Support is there, though, so I guess it should work.
