I was helping my dad put together a surround sound system in his living room when we ran into a problem. Here's what he have
DYNEX TV DX-40L130A11 (not sure which exact model in range)
LG Blu-Ray Player BD530
Technics Stereo\Surround receiver SA-DX1050
HDMI and Optical cables

The Blu-Ray was hooked up to the TV via HDMI cable. The TV was hooked up to the Stereo via Optical cable. We tried various adjustments to the audio setups of all the devices going between PCM decoding and DTS decoding. But, we could not get the surround signal going into the receiver via this setup.

After tinkerings of various kinds, I had the inspiration of directly connecting the Blu-Ray to the Stereo via a digital coax connection just to see what it would do. I then played some demos in DTS and Dolby individually. The receiver picked up the DTS and Dolby signals and switched over to the proper decoding settings (Dolby for Dolby and DTS for DTS).

Now, I know the optical cable can handle the surround signal. I've tested that before. As for the HDMI, it is suppossed to be capable of handling the surround signals. But, we are now in doubt. Any input would be welcome.

Update: I was unable to find additional information in the manual for the TV. However, I have a similar setup for my TV and was able to find some information in my TV's manual. Apparently, the optical out connection on the back of the TV only emits 2 channel stereo (on my TV, anyways). It said that if I wanted surround sound, I would have to directly connect the player to the receiver.

(Note: I am saying that the optical out on the TV is emitting a stereo signal instead of surround. I am not saying that optical can't handle surround.)
