Go to console settings from the dashboard and make sure notifications are turned on.

Hey Biggest, sorry to hear about the connection issues! This sounds a lot like a NAT issue (for which we have
this guide), but let's see if we can locate the source of the issue. Can you connect to other players without issue? Can your friend connect to other players without issue? Please let us know!

Hi There,

See if there is anything in the trouble shooter that can help you out.

If you can hear others in a party or game but they can't hear you, try these solutions.

Solution 1: Make sure your headset is not muted

Check that the orange LED light next to the mute button is not on.

Solution 2: Power cycle your Xbox One console

For help, see How to restart or power cycle your Xbox One console.

Solution 3: Re-associate your controller with your profile

1. Press the Xbox button  to open the guide.
2. Select System > Settings > Kinect & devices > Devices & accessories.
3. Under Assigned to, choose your gamertag.

Solution 4: Verify the NAT type for your network

Network Address Translation (NAT) lets you hide your IP address from devices that are not on your network. For more info about NAT, see the "Current network status" section at Network
settings on Xbox One.

Solution 5: Test your Xbox One Chat Headset

To test the headset, start a party (requires internet connectivity) to test the audio:

1. Sign in to Xbox Live on your Xbox One console.
2. Press the Xbox button  to open the guide.
3. Under Multiplayer, select Start a party. (You don't need to invite anyone for this test.)
4. Make sure your mic is not muted in party chat.

Note You can use the Y button  on your controller to toggle mute on or off.

1. Make sure your headset is not muted and that the volume is turned up.
2. Speak into the microphone. If your headset is working, you’ll see the ring around your gamerpic light up.

If you still can't hear your friends online after you've started a party, but you can hear sound while using in-game chat or another app like Skype, see You
can't switch to party chat on Xbox One.

Solution 6: Troubleshoot your connection

Check your connectivity by using the Xbox One Multiplayer Game Solution

I have no sound when i play my games, others can hear me talk and i cant hear them. I get sound when i am at the dashboard making selections...wtf???

ive had this problem as well on my xbox. I did a full shutdown of the xbox and unplugged everything in the back for 20 minutes. Seems to hard reset everything and my xbox goes back to normal. See if that works for you too.

Sounds like you're under a communications suspension. You can log in at
http://enforcement.xbox.com and click the orange hammer to see the details of the suspension, including the rule that was broken and when it ends. If you feel the suspension was issued in error and it lasts longer than 24 hours, you can request a case
review there and the enforcement team will take a second look.
