Question about blu-ray audio tracks

I have recently discovered that for blu-ray discs that do not contain a separate 5.1 DTS or DD soundtrack (i.e., blu-ray discs that contain only DTS-HD lossless or Dolby TrueHD 5.1 soundtracks), my system defaults to stereo and I cannot figure out how to get digital surround. Shouldn't the DTS-HD or Dolby TrueHD soundtracks be downmixed into 5.1?

I have a Panasonic Blu-ray player connected via coax to an older Theta Casanova pre/pro (DD, DTS only). I assume it must be a setting in either the Theta or Blu-ray player that is causing this but haven't been able to correct it.

Any ideas?

Thanks

Re: Question about blu-ray audio tracks

What is your coax output set at in the player? Bitstream or PCM?

Yes. Link: Dolby Technology - Dolby TrueHD for High Definition Media Audio and Video

Re: Question about blu-ray audio tracks

Dolby TrueHD



Dolby® TrueHD is Dolby’s next-generation lossless technology developed for high-definition disc-based media. Dolby TrueHD delivers tantalizing sound that is bit-for-bit identical to the studio master, unlocking the true high-definition entertainment experience on next-generation discs. When coupled with high-definition video, Dolby TrueHD offers an unprecedented home theater experience that lets you enjoy sound as stunning as the high-definition picture.
Features

* 100 percent lossless coding technology.
* Up to 18 Mbps bit rate.
* Supports up to eight full-range channels of 24-bit/96 kHz audio.*
* Supported by High-Definition Media Interface (HDMI™), the new single-cable digital connection for audio and video.
* Supports extensive metadata including dialogue normalization and dynamic range control.

*Dolby TrueHD can support more than eight audio channels. HD DVD and Blu-ray Disc standards currently limit their maximum number of audio channels to eight.
Benefits

* Delivers enthralling studio-master-quality sound that unlocks the true high-definition entertainment experience on next-generation discs.
* Offers more discrete channels than ever before for impeccable surround sound.
* Compatible with the A/V receivers and home-theaters-in-a-box (HTIBs) of today and tomorrow.
* Dialogue normalization maintains the same volume level when you change to other Dolby Digital and Dolby TrueHD programming.
* Dynamic range control (Night mode) enables you to customize audio playback to reduce peak volume levels (no loud surprises) while experiencing all the details in the soundtrack, enabling late-night viewing of high-energy surround sound without disturbing others.
* Selected as the mandatory format for HD DVD and as an optional format for Blu-ray Disc.

Re: Question about blu-ray audio tracks

It'll happen when a Dolby supporter like George Lucas decides that, say, the Star Wars movies would sound better in 7.1 True HD and gets Skywalker Sound to remix and remaster accordingly, or if someone decides to prep a 7.1 track for a new release in True HD.
