We can assume it does support it because linux is picking it up (and your not complaining of no sound ).... but I would have thought that would be clear in the specs as a selling point... anyways I digress

do this at the cli and paste in here:

Code:
sudo dmesg | grep HDMI

That will show us what is supported on your HDMI connection. You may also need to configure your TV as anynet + - cec connection (if your tv supports it), and again if your tv has the option, set the speakers to external. Also check any HDMI connection setup options in the Onkyo - you may need to enable some of them.

What happens by default is the edid information gets passed through the receiver to your PC, and linux/windows picks up the TV's audio information, instead of the receivers - hence your only seeing left and right, and depending on the output of dmesg you may be getting limited "HDMI: Supports...." output if that's the case.

So by enabling anynet+ - cec your tv will detect that it's connected to a receiver and the receiver's audio information will be passed to the PC instead.

For example here is my dmesg output when I have booted linux with my receiver turned off:

Code:
HDMI: detected monitor SAMSUNG at connection type HDMI HDMI: available speakers: FL/FR HDMI: supports coding type LPCM: channels = 2, rates = 44100 48000 88200, bits = 16 20 24

and here is when I have booted my PC with the receiver on:

Code:
HDMI: detected monitor SAMSUNG at connection type HDMI HDMI: available speakers: FL/FR LFE FC RL/RR RC RLC/RRC HDMI: supports coding type LPCM: channels = 2, rates = 44100 48000 88200 176400 192000 384000, bits = 16 20 24 HDMI: supports coding type LPCM: channels = 8, rates = 44100 48000 88200 176400 192000 384000, bits = 16 20 24 HDMI: supports coding type AC-3: channels = 6, rates = 44100 48000 88200, max bitrate = 640000 HDMI: supports coding type DTS: channels = 7, rates = 44100 48000 88200 176400 192000, max bitrate = 1536000 HDMI: supports coding type DSD (One Bit Audio): channels = 6, rates = 48000 HDMI: supports coding type E-AC-3/DD+ (Dolby Digital Plus): channels = 8, rates = 48000 88200 HDMI: supports coding type MLP (Dolby TrueHD): channels = 8, rates = 88200 192000 HDMI: supports coding type DTS-HD: channels = 8, rates = 88200 192000

Notice it's still says Samsung for the monitor, but it is picking up the audio information from the receiver correctly. As long as that is happening for you then don't worry if you can't see Onkyo anywhere in the output.

@mightymouse2045 - thx for reply.
For test I installed windows 7 and I ran movie with the same connection: hdmi from my box to receiver and from receiver to TV.
In sound settings under windows I saw my onkyo receiver and I choosed it. When I played movie with soundtrack DTS-MA I saw this on my onkyo 608 Smile

It's working very well.

Under linux with XBMC I haved sound bun only DTS.

Info about HDMI when XBMC is starting:

The same results I had when I changed in my TV speaker settings: internal to external....

Put Nvidia graphic to box and connecting hdmi from receiver:

So question is, why if I connected HDMI to onboard I didn't get the same results?
