Problems With Uncompressed Sound!!!

[NRIQ]

When I activate the Uncompressed sound, my receiver indicates that its a 2. 1 surround sound instead of a 5.1 uncompressed sound. I have it connected to the BD player with an Optical Cable. Why could this be happenning? And how could I resolve it? Is it my home theater is a little old now? Is it the connection is badly installed? Is it the set up on my bd player is incorrect also? what could it be? PLEASE HELP!

have to have it connected with HDMI. Optical will only do 2.0.

Sounds like you are trying to pass uncompressed audio through an optical cable, can you use HDMI instead? That would fix you up...

Thanxsz for the help guys! I guess that´s it! I´ll have to upgrade to a home theater with a HDMI IN acces... cuz mine doesn´t have one... I guess that was the problem all along... Jejejejejeje! Now... Another question... is 5.1 Uncompressed better than DTS Sound?

Yeah, basically you always want uncompressed (aka lossless) audio over "lossy" audio tracks. PCM 5.1 is better than DTS 5.1 (but not necessarily better than DTS-MA 5.1, which is lossless).

what bluray player are you using?

The lossless digital master audio is lossless PCM 5.1. DTS-HD MA 5.1 is lossless compression processing of the master audio which is lossless PCM. How can DTS-HD MA be better than lossless PCM? Thus if you have a BD that has both lossless PCM 5.1 and DTS-HD MA audio tracks, they both should sound identical.

You are correct if you are referring to lossy DD 5.1 or DTS 5.1 decoded to PCM 5.1. This time the PCM 5.1 is not a perfect copy of the master audio because audio data was lost during the lossy compression process.

I think, with certain titles, you'll notice a HUGE improvement over lossy sound. Don't get me wrong... DTS sounds great and has served its purpose well but uncompressed audio, DTS-HD MA, and Dolby TrueHD sound AMAZING!

You just said the same thing as the guy you quoted, just with more words. He didn't say DTS-HD MA was better than PCM. He said PCM was not necessarily better than DTS-HD MA (or to put it another way, they are equal as long as the are sourced from the same mix).

Yes, that's what I am saying, or put another way:

Lossless PCM (the original lossless audio source) = DD TrueHD = DTS-HD MA
