Privacy settings - Sea of Thieves

That's odd, only with Sea of thieves, right?

Could you try disabling and enabling all your privacy/multi-player settings?

I found the solution actually.

Go to Settings -> Privacy -> Background Apps

Turn on the Xbox app and any other applications you want to work in the background (including Sea of Thieves)

Sea Of Thieves Xbox One Audio Chat
On Xbox One, this Sea of
Thieves error has plenty of solutions. However, the first thing that Rare recommends is to try to reconnect the device, whether that be a headset or the Kinect.

Players must also ensure that the device is not muted. For Kinect, there's a "Kinect mic for chat" option in the Settings menu while it is connected to the console. This must be set to On to activate the microphone.

Like in Windows 10, the privacy settings must allow voice communication and allow Sea of Thieves to access the microphone. For the first setting, players must go to "Settings" > "Account" > "Privacy
and online safety" > "Xbox Live privacy" > "Communication and multiplayer" > "Voice, text, invites."

To allow the game to access the microphone, players must choose "App privacy" after "Privacy and online safety." From there, the "Microphone" setting can be adjusted.

Rare also acknowledges the issue wherein players join a Party Chat, but they cannot communicate.

"Players who don't accept the invite or join the crew late are not automatically added, so they may believe that their chat isn't working and their crew is silent," says Rare.

The solution is to try the steps outlined above.

Following these steps should take care of the Sea of Thieves voice chat issue on the Xbox
One. If there are still problems, players are encouraged to report it to Rare.
