Xbox Insider Release Notes

Known Issues for Alpha

We understand some issues have been listed in previous Xbox Insider Release Notes. These issues aren’t being ignored, but it will take Xbox engineers more time to find a solution. We appreciate your patience at this time!

Audio

  • Users who have Dolby Atmos enabled and console display settings set to 120hz with 36 bits per pixel (12-bit) are experiencing loss of Dolby Atmos audio in some situations.
    • Workaround: Disable 120hz or set Video Fidelity to 30 bits per pixel (10-bit) or lower.

Messaging

  • Users are unable to send a voice message while in Parties.
    • Workaround: Send the message while not currently in party chat.

Profile Color

  • Sometimes users may encounter the incorrect Profile color when powering on the console.
