I'm having a weird audio problem. I have my unit set up this way: HDMI video to my XBR2, and coaxial digital audio to my Sony STR-DE985 receiver. The receiver can do Dolby Digital EX (3/3.1) and standard DTS (3/2.1). I have Dolby and DTS set to Direct on the BDP-S350 player.
With DVDs, Dolby and DTS both work fine, but virtually every Blu-ray disc I've tried has major drop-outs on the Dolby track. And it's not just during the main content - some of the Disney DVDs have a little intro screen in Dolby Digital, and that breaks up, too. And by breaks up, I mean that the receiver seems to lose and regain the Dolby signal. The picture, on the other hand, is rock-solid no matter what.
To complicate matters, I have two Blu-ray discs which have no high-resolution audio: The Last Samurai (Dolby 5.1 English and French, Dolby Digital 2.0 Spanish) and Planet Earth (Dolby 5.1 English only). The receiver plays the Dolby Digital stream flawlessly.
Now, to further complicate matters, if the disc has a DTS track, it works fine. The player downconverts from DTS-HD MA to core DTS and the receiver plays the DTS stream flawlessly. DTS should be coming out of the player at 1.5 Mbps (or at least 750 Kbps). This means that it's not bitrate per se that's the issue. Also, the highest rate that Dolby Digital can use is 640 Kbps, so if The Last Samurai is really encoded at that rate, then there must be some subtle difference between the way the player outputs a native 640 Kbps Dolby Digital stream and the way it downconverts a TrueHD stream to 640 Kbps Dolby Digital.
I tried a different coaxial digital cable, and I even switched to an optical digital cable. I get the exact same results every time.
Does anyone have any thoughts or suggestions?
