There are not many known issues with XBox One‘s audio settings.  Fortunately, when there is an issue, it’s not because of the hardware. There are a few things you can try before contacting Microsoft.

Possible Fixes

The issue with your audio could be one of a couple of things – from a bad connection to a software setting. The good news is, this may not cost you anything to fix. The bad news, it may cost you up to $20 for a new cable.

  • Go into your Settings > Display & Sound > Audio Output. Select the audio format that you’re using with your console. If you’re unsure, select Stereo Uncompressed. Personally, I have both options set to Stereo Uncompressed because I’m weird like that – you don’t have to be weird like me, but no one will judge you if you are. 🙂
  • So you checked and made sure everything was connected like it’s supposed to be – both ends are nice and snug in their rightful ports. If you’re still having problems, then you may need a new HDMI/Optical cable. When you buy a new cable, make sure to keep the receipt, just in case that’s not the problem – because if it’s not, it’s time to contact Microsoft (return the cable after you talk to MS).
  • If you connect your console to the cable box directly, unplug everything – the XB1 and the cable box.  Wait 30-60 seconds, give the cache time to clear, then plug everything back in.
  • Some cable boxes have their own audio settings, for this you’ll need to check with your cable/internet provider.

The above should help get your sound back on and/or working properly, if not then you’ll need to take your XB1 in and have it checked out.
