Would an optical audio cable to hdmi work for xbox to tv?

It sounds like you setup is more difficult that it needs to be. HDMI cable does both HD audio and video whereas the fiber optic does hd audio. I would try hooking the HDMI cable is connect to the tv and the fiber optic to the amp

Hi rsugden93,

Sorry you're having issues with your sound. To help narrow down the issue you should try removing things to see what could be the issue. If you're using optical audio, can you unplug this and just use the HDMI audio from the TV? If this works with
no issues, then it's likely something with the optical audio (cable, connection, dirt, ect). If you hear it on the TV after removing the optical cable, then try a new HDMI cable. As this is a random issue, it's likely something on the receiver, cable, or TV
side, and not an Xbox setting.

Hope this helps!

I have digital audio working.

Cable HDMI to XBox One

XBox One HDMI to TV (display only)

XBox One Optical out to Sound bar (Bitstream Dolby)

I have the same issue. HDMI from x box one to TV monitor LG No sound. And in the settings for audio it will not let me select hdmi audio, optical audio only. I have an optical cable connected to x boxing and tv optical in And still no sound.

Hi, how do you have the optical cable routed, if you're taking it from the Tv to the A/V unit odds are you will only get stereo audio. The best option is to connect the optical cable from the Xbox to the A/V unit.

You would also of course need to go into the audio output settings on the Xbox and turn off HDMI audio and switch to optical audio.

Just had a quick look at the user manual for that A/V. It has 2 optical inputs so you could run one optical cable from the Tv to the A/V port that's marked as Tv Audio and run another optical cable from the Xbox to the optical input that's marked as Media
Player. You may also need to check the A/V unit is set to output digital audio on that Media Player port. That could be as simple as selecting the audio format on the remote control.
