Like I said earlier, depending on the TV, it may or may not be able to take an audio input and pass it back without changing it to two-channel audio. Most TV sets do not accept a 5.1 input via optical/coax and then loop it back as 5.1. The TV processes the audio for two-channel, so that's all it's going to spit back out via optical/coax. Audio received via OTA doesn't suffer from this (TV manufacturers know that people want to send 5.1 to their receiver) and can be sent directly to a receiver in 5.1 format.

In the same token I have my STB connected to my HLS4266W TV via HDMI. When I tried to connect the TV to the receiver via the optical out on the TV, the output was a PCM signal rather than 5.1 and only allowed stereo sound.

Will most recievers allow you to use the HDMI switching function to pass video and still have the audio come from the optical or coaxial digital while passing video through HDMI?

Wow, lots of misinformation flying around in this thread. You guys are lucky kegobeer came in.

HDMI is superior to optical and is the only way you can take advantage of Dolby TrueHD and uncompressed PCM on the PS3 (when watching Blu-Ray movies.) I don't know if there are any games that take advantage of DTHD or PCM, but it'll definitely improve the audio of some BD discs.

Watch out for receivers that only support "HDMI passthrough" as they will only send the audio to the TV - the receiver won't play the audio.

I linked this thread on the AVS forum up to post 8 and they said every single post was wrong so be careful.

I have been using an optical for the longest time and cannot tell the difference in quality using B&W loudspeakers.
When will 1.3 be available?

Which is why I posted that there was a lot of misinformation in this thread. People who don't know about the technology should not respond as if they do. It only hurts others on here.
