Do I use an Optical Cable with an HDMI cable, or one or the other?

Question

I have it all hooked up for my 5.1 surr system to my AV Receiver, but do I use the optical cable, which I already have, with the HDMI or does the HDMI feed do the surround sound, all this is for a PS3.

Answer 1

As far as I know you need both the HDMI and the optical cable for a PS3 to get both sound and picture. It is an incompatibility issue between the HDMI and the receiver.

Answer 2

If your A/V receiver has HDMI inputs, you do not need to use the optical audio cable.  The audio comes in on the HDMI.

Answer 3

it depends. does your receiver support hdmi pass through?

if it does then you will need both the hdmi cable and toslink.

if it doesnt, then you just need the hdmi.

Answer 4

You need optical cable if your receiver not compatible. What is the model of receiver ?
