PS3 dts cd music playback

Fongolio

I originaly posted this in Video Games but am posting here hoping someone will have a clue as to what to do. I recently purchased a Sony Playstation 3 for Blu-ray disk playback gaming and entertainment center. Everything else is awesome. I hooked up an external 500 gig usb hard drive and have all my pictures mp3's (rarely played anymore) movie files etc. on one drive that plays through the PS3 to my home audio setup. The problem is when I try to play a dts cd. I have read extensive forums online and have changed the audio cd output frequency from the default 48kHz to 44.1/88.2/176.4 setting in the music settings area. Then, in the sound settings audio output settings area I have set sound to optical (which I am using) and unchecked all other settings. I have optical set to bitstream. Here is where the problem is..Linear PCM 2 Ch.48kHz and Linear PCM 2 Ch. 44.1kHz are both grayed out. I need to uncheck 48kHz in order for correct signal for dts cd be sent to my receiver. I have tried every combination and nothing will highlight that box so that I can uncheck it. I have the latest firmware as well. In other forums people are saying that they can play dts cd on PS3 but all I get is the static sound of non-decoded dts. Please help.

The setup:

Pioneer Elite VSX-52TXi 7.1 Receiver
Polk Audio RTiA7 Fronts
Polk Audio CSi40 Center
Klipsch RF-25 Surrounds
Polk Audio RTi70 Surround backs
Pure Acoustics RB 1150 Active Subwoofer X2 (one on each side of room)
Hitachi 42HDS69 Plasma Screen
Pioneer DV-400V DVD player (for divX playback)
Pioneer Elite DV-79AVi DVD player (for sacd, dvd-audio and dts audio playback)
Oppo HD981 DVD player (universal player)
Sony Playstation 3 for Blu-ray and music server
Bell ExpressVu 9200 HD-PVR Satellite Receiver
Monster Cable speaker cables and interconnects

from HERE

"dts 5.1 Music Disc (dts-CD) is supported if 44.1kHz is selected as the only output frequency, and you use an external decoder. Choosing 44.1kHz can be done via the "Music Settings" and "Sound Settings" inside the "Settings" menu of the XMB. The PS3 normally treats all CDs as unencoded Linear PCM and will just take the Linear PCM untouched from the CD and send it down the HDMI or TOSLINK, or convert to analog first before sending it down the AV Multi cable. Because the dts-CD Linear PCM on the CD is actually encoded 5.1 channels (or 6.1), you must trick the PS3 into sending the data untouched to an external dts-CD decoder via HDMI or TOSLINK (NOT the analog AV Multi). To accomplish this, you must turn off upconversion (48kHz, 88.2kHz and 176kHz must not be selected), otherwise, your signal will sound like FM noise."

I don't have any DTS-CD's so I can't try this myself to see if it works. Sounds like you did all of this already but maybe you can find something you missed. Hope it helps.

Yes, tried it all. Twice. Thanks for the suggestion though. Any help is appreciated.
