Xbox One Insider Preview build 15051 now available in the Alpha ring - here's what's new

A new build is available for Xbox One consoles in the Preview Alpha ring of the Xbox Insider Program, bringing the build number to 15051.1001, or rs2_release_xbox_1703.170305-1701.15051 is also the build number of today's Windows 10 Mobile Fast ring release.

It doesn't contain any new features, as the Creators Update is right around the corner, as it's slated to ship in April. Instead, it contains one fix, and as always, a bunch of known issues. Over the next month, we can expect to continue seeing these builds that are focused on fixes, until the Creators Update ships and we start seeing Redstone 3 builds.

Here's what got fixed:

  • Games & Apps
    Fixed an issue which could sometimes prevent newly installed games from launching.

Here are the known issues:

  • Controller

    Upon resuming from connected standby, you may be prompted to update your controller firmware when no update is available.

  • Cortana
    Cortana may take a long time to respond when activated while playing certain games.

  • Notifications
    Some users may not receive certain types of notifications.

  • Game Clips
    After capturing a game clip, the game clip fails to automatically post to the Activity Feed (if your profile is configured to do so).
    Workaround: Manually view game clips in Profile > Captures > Manage captures and post to the Activity Feed.

  • EA Access
    The EA Access app may indicate you are not an EA Access subscriber when you are. This does not affect your ability to download or play games from the Vault, or receive discounts on EA titles.

  • Screen Dimming
    The screen may dim after a short amount of time while viewing videos in certain apps (Hulu Plus).

  • Settings - Ease of Access
    When enabling the Mono output setting in Ease of Access - Audio, Settings becomes unresponsive, crashes, and fails to launch on subsequent attempts.
    Workaround: To launch Settings, perform a hard reset (hold down the button on the front of the console for five seconds until it fully powers down, then power it back on).

  • Settings - Display & sound
    The Audio output page is under construction and some of the new settings are not yet functional. New support is planned for Dolby Atmos for home theater, Dolby Atmos for headphones, and more in upcoming builds. An announcement will be made when these new features are ready to try out; enabling these settings now will have no effect.

  • Wireless Display
    The Wireless Display app fails to launch and immediately crashes to Home.

While Preview Alpha is set to receive two to three builds per week, this will likely show up on Beta tomorrow, which is supposed to see one or two per week. If you're on the Alpha ring, you can grab this update by heading over to Settings -> System -> Updates. If not, you can work your way up by completing Quests and Surveys in the Xbox Insider Hub.
