Optical Cable / 5.1 Surround Question

Hopefully this makes sense....

I have a PS3, 360 and plasma TV. Sound is currently running through the TV's standard built in speakers (boo)

If I want to run it via a 5.1 system I would do so via an optical cable. However most systems I have looked at only seem to have 1 optical input.

My question is: Can I run the optical from the TV to the 5.1 system and get true 5.1 whilst playing Xbox / PS3 or do I need to run an optical cable from each device?

Confusing to what you want? if you mean the tv has optical then it wont be more than 2.1.

So if I want to get true 5.1 from the PS3 and Xbox I would need an optical cable from each going into the back of the 5.1 system?

Surely you need a receiver?
then use HDMI from each device to receiver, then HDMI to TV

HI,

My set up is similar to yours, PS3, Sky HD and a Wii.

The set up I have is as follows:-

LG TV and LG sound system, (tall boy speakers)

Optical from Sky HD goes into Sound system amp/ DVD player. (sound still enabled on HDMI too incase for what ever reason i did not want system on)
PS3 HDMI cable into INPUT HDMI socket of amp/dvd player.
Wii on component into TV with extension lead on Coaxial audio into amp.

Sky and PS3 on full 5.1 and wii on emulated (virtual) surround managed by the amp.

I then just select the output i require on the amp to output via HDMI the config I require (expect the wii on component)

Im happy with the setup and quality.

Rick

If you get an amp that takes audio over HDMI then you would just run PS3 and 360 via hdmi to the amp and a single hdmi to the TV.

I have a similar set up to Rick, or will have when my gear arrives tomorrow. I have a 5.1 Samsung system that I will hook up to the amp. I also have Sky HD, PS3, Xbox 360 and an Acer Revo. If I hook the previous 4 up to the amp via HDMI and the 5.1 via optical, will I get 5.1 on all my outputs? This is the amp I am getting but I cant tell if it takes audio over HDMI. Thanks.

HDMI is better than optical for sound anyway.

How do the amps/ setups distinguish between the 0's and 1's ?

I already know what I'm tallking about. It appeared you were saying hdmi 5.1 is better than optical 5.1 which it is not as it's all 0s and 1s and the connection makes no difference to digital . You are also very wrong about 7.1 I have a 7.1 setup and optical connection is fine for 7.1

I asked you how they distinguish the difference between them ?

Be funny if you knew what you were talking about, go do some googling sunshine. Optical doesn't have the bandwith for DTS-HD, Dolby Digital HD, so 7.1 audio, you need HDMI to be able to carry it. Damn you look stupid now.

if you have a receiver that only has one optical input, put everything into tv, and take optical from tv to receiver. i (possibly wrongly) assume all the sound should pass through tv to receiver.

And just so it's clear mike DTS-HD / Dolby TrueHD, Dolby Digital Plus does need HDMI 1.1 > / via lpcm / 1.3 > for TrHD 7:1 bitstream. It can be dished out over RCA/ Analogue / using internal DACs.

7.1 Dolby Digital Ex (over optical) as above I use it.


Check what Dolby have to say http://www.dolby.co.uk/consumer/understand/playback/index.html

It's certainly possible. Completely depends what TV it is though.
