The issue with the audio could be one of several things, ranging from a software setting to faulty connections. The bad news is you may need to purchase a new cable or two (or call Microsoft and wait for a replacement), but the good news is that it may be as simple as changing your options.

The first step should be to go into the Settings and select Display & Sound. From there choose the option that reflects your system either HDMI or Optical and then select the audio format that suits your system. If you dont know, select Stereo Uncompressed.

Lets assume youve confirmed everything is connected properly. If you are still having issues, it may then be a matter of a faulty optical or HDMI cable. Replace it and see if that fixes it, but keep your receipt. If it doesnt work, you can always return the cable after contacting Microsoft.

If you are connecting your Xbox to a cable TV box, unplug everything the Xbox One and the cable box and then wait 30 seconds for the cache to clear.
