Default A3 audio issue..

I have my A3 connected to an Onkyo 605; both claim to be able to decode Dolby TrueHD, yet anytime I play an HD-DVD with a trueHD track, the receiver and player both show PCM as being output, is there a setting I need to change? Any help is appreciated; the receiver and player are connected via hdmi 1.3...

As referenced in a prior article here on High-Def Digest in connection with next gen audio formats, the A3 is in the category of HD players that cannot pass on Dolby True HD in a bitstream format to your receiver for decoding. However, the player is able to decode the Dolby True HD and pass it on to your receiver as multi-channel PCM.

This is also referenced on page 21 of the A3 owner's manual. The detail provided under the "Auto" setting for the "Digital Out HDMI" function indicates that the A3 has the ability only to bitstream the legacy Dolby Digital and DTS formats, not any of the next gen formats. You should also note that while the A3 is able to decode both Dolby Digital Plus and Dolby True HD into PCM, it cannot decode DTS-HD or DTS Master Audio. When encountered, both of the next gen DTS formats are reduced to their DTS core and then output as PCM.
