Screeching sound in party chat, game chat mic sounds crackly to others

Hi there JohnLS5150,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with sounds in your party chat.
I recommend taking a look at the following troubleshooting articles:

• Connecting a compatible headset to Xbox One
  
• Xbox One controller and headset compatibility
• If you hear an echo or noise during gameplay
  
  • Note If you hear an echo effect, it often originates from the person who is talking and not necessarily from the person who hears the echo. For example, if you hear an echo only when someone else talks, the problem may be with
    the headset connection of the person who is talking.

The following conditions may cause an echo or noise during gameplay:

• The microphone detects ambient noises. This includes voice transmission that comes from the earpiece.
  
• The headset plug is not fully inserted into the controller.
• You’re using the Xbox One Wireless Controller, and the battery levels in the unit are low.
  

If you or other players hear an echo or other noise during gameplay, try the following:

• Turn the volume down on your TV or stereo.
• Disconnect the headset, and then reconnect it firmly to the controller's expansion port.
  
  Note Never pull on the headset cable when removing it from your controller. Remove your headset from your controller by pulling on the body of the headset plug.
  
• Clean the plug on the headset cable with a clean cloth, and then reconnect the headset to the controller.
  
• Test the headset by connecting it to a different controller.
• If you're using an Xbox One Wireless Controller, replace the AA batteries or recharge the Xbox One rechargeable battery.
  

An important configuration which enables all features and enhances the online experience is the network connection on the Xbox One console.

Give this a try and let us know the results.

Hi Ricardo, thanks for the suggestion!

I don't quite understand - so you turn the volume down on the console and up in the game?

Thanks!

Hi there,

Thanks for your reply. As I have mentioned in other replies, I have gone through all of the related (and other) troubleshoot guides to no difference.

What would constitute sufficient connection? I have a download speed of 24 mbps, upload of 4,5 mbps, latency of 24 ms, 0% packet loss, and MTU of 1480. Is that not good enough?

Thanks!

It happens no matter who I am with in the party - I have tried it with three different individuals and the result is always the same (I generally only play with one person at any time).

Although I should mention that the one time when two others joined the party, then it became normal...

Do you have the console over LAN or WLAN on the run?

did you pick it up with a Mixamp as it is with an Astro A40?
