Technical question about the PS3 and Dolby TrueHD

[Midwest]

I work for a technology integrator in Minnesota and ran in to a bit of trouble with a clients PS3.

In short, I can't get an Integra Reciever to output Dolby True HD. It's this reciever...

All settings are correct on the reciever and it is hooked up through a 1.3 spec HDMI compliant cable and jacks.

It is a brand new PS3, only thing I could think of would be lack of a firmware update but I thought it came ready to go out of the box for Dolby TrueHD.

What settings need to be enabled on the PS3? I enabled all of the available audio output options including the ones found in the BD playback menu.

On a side note, can the ps# do DTS:HDMA?

Also can it output audio through an optical cable and use the HDMI for video?

Any takers on these? I am stumped.
