Respected All Senior Members
I have Tata Sky HD+ STB with LG 32 LCD. My STB is connected with HDMI cable and my LCD has Optical out with dolby digital decoder inbuit but my speakers (Z506) does not have optical in. I want to make only true 5.1 home theater and dont want to spend too much money. Pls help.

They do make Optical to Analog converters.
Though mostly are stereo analog.
To get one that does 5.1 it is going to be expensive. If you can even find one.
I added a separate reply below.
It will take the optical output from the TV and convert it to analog stereo. That can be used with the Logitech Game Adapter to get all three of the input cables on the Z506 connected.
I have no actual use information on it, but it most likely would not be true 5.1 but simulated.

This is an example of a optical to stereo analog converter. There are others. This one takes an optical signal that has 5.1 dolby and down converts it to stereo analog.
This one does an optical stereo to analog stereo.
You could then see if you could find a Logitech Game converter. To take the stereo analog and simulate it into 5.1 for your Z506.

I have a similar question where my TV only has a dolby digital audio out, I was wondering if paired with the Turtle Beach Ear Force DSS if this would decode the signal so I could use these speakers with my tv?

The Z506 speaker system relies on your computer to decode the audio. This is why the speaker set uses three 3.5mm cables to connect to their audio source. One cable is for the front left and right, one is for the front center, and the third is for the rear left and right. It looks like the Turtle Beach Ear force has only one 3.5mm output (headphone) jack on it. You would be in the same situation and will not get true 5.1 surround sound. You can get simulated surround sound by only plugging in the green 3.5mm plug to the source. The speakers will automatically simulate surround sound.
I hope this helps you out.

etcetera; I found the users manual for the processor you linked to.
It may not do what you want.
First it is powered by a USB port. So you will need a USB port to power it.
It does look like it will decode the optical Dolby signal to a stereo headphone level output.
You could use the green plug and simulate 5.1. As Logitech Support indicated.

I've got a similar query... I have an external sound card for my laptop with an SPDIF IN (and out) and a 6-channel audio out. The laptop runs my pc games in 5.1 through the card but I'm looking for a way to use my Xbox 360 via the SPDIF ports with 5.1 surround. Simply connecting and setting the laptop to 'listen' doesn't do the trick as it isn't decoding the dolby digital.
Do you know of any way to either tell the computer to decode it then play it, or of any software which could do this for me?
Any ideas/suggestions would be appreciated.
