Audio Lag from 5.1 Optical output from XBOX ONE X

I had to goto my DVR box and under audio output select HDMI over PCM or Auto.

Then I ran my optical cable from the XBOX to the receiver, the receiver is set to optical input. Also I don't believe the xbox one support 5.1 yet, so you'll need to make the DVR output Stereo or DTS.

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

Found this digging through Logitech Info, hope it helps!

The XBox 360 only outputs 5.1 over HDMI or optical, so what you need is to convert from that to the 3.5mm 5.1 channel audio line-in that your speakers need. A converter box may be very expensive; however, you should be able to find an audio/video receiver
(also called a "home theater" receiver) that will take HDMI inputs and output the audio in different formats (i.e. output your audio to a 3.5mm and let you still use HDMI for video).

That's simply incorrect. The Xbox One has output surround sound since its release-- DTS and 5.1/7.1 uncompressed multichannel PCM over HDMI. Until the last update, it did not support outputting a compressed Dolby Digital bitstream, which is what is needed
for optical (because optical can't carry uncompressed 5.1/7.1). It does now, however.

OP, it sounds like you are selecting 5.1/7.1 uncompressed, which is not supported by TVs (that is for a receiver (AVR))--and that is why you can't select it when HDMI is set to Auto. Most likely your TV is just seeing it as 2.0 (stereo) audio. You need
to set the Xbox One audio to bitstream with Dolby Digital encoding. Even then, please be aware that very few TVs pass DD 5.1 from an HDMI source out though the optical out. What you may end up getting is virtual surround sound, not true discrete 5.1.

"I like to play games and watch movies with an Astro surround-sound headset, which decodes Dolby 5.1 audio from an optical input cable. However, the Xbox One is currently only able to output stereo and DTS Digital through its optical output. My headphone
receiver can't read DTS Digital, so I have to output in stereo, and my surround headphones turn into regular old headphones. I've been asking Microsoft for the last week if they intend to add Dolby output to the optical audio port in the near future (it's
an option for HDMI output), but haven't gotten a solid answer on whether a fix is coming."
