5.1 Optical Audio Output broken

did you got. an andere? I have the same Problem.

I just comment on bluray and optical discs(but might be valid of online streaming as well).

There are usually many audio options for media itself - you might have 5.1 on some sources and not others - and both 5.1 and stereo as well.

And on some stereo is default - and you have to set to use 5.1 etc - it might be there on disc.

I stopped using Xbox for media, does not compare to standalone media players.

All standalone have many settings I never saw in Xbox - like how 5.1 are to be mixed to stereo or output as it is etc.

You should always be able to get audio everywhere on all channels if proper settings exist -as they do on standalone players.

Did you look for settings like that?

Hi Darkstar,

The Xbox is working 100% as it should be. If the Xbox source signal is 5.1 i.e a game, then the audio stream to the receiver is 5.1 and the receiver will output 5.1 audio to the speakers. However if the Xbox audio source signal is 2.0 i.e music, then the
stream to the receiver is 2.0 and the receiver will not magically output 5.1 audio to the speakers.

This situation will happen for HDMI or optical using DTS or Dolby decoding etc. The Xbox will not simulate 2.0 up to 5.1. You will need to use one of the surround effects (simulation) on your receiver to scale the 2.0 audio to 5.1 audio. Sorry its not what
you want to hear, but this is how it works

I doubt you'll get true 5.1 sound using the red and white cable as they are only stereo. Does your sound system have an optical audio input that you could connect the optical audio output of the console or tv to at all?

It isn't possible for any TV to pass through uncompressed 5.1 audio but they can pass through Dolby Digital 5.1 format which is compressed.

What you need to do is tell the Xbox to output Bitstream audio via HDMI and set the Bitstream format to Dolby Digital. If you do this your TV will be able to send the 5.1 surround audio to your soundbar via its optical cable.
