Here's what's new, fixed, and broken in Windows 10 Build 14931

Microsoft just pushed out a new build of Windows 10 to Insiders in the Fast Ring for PCs. The company today released build 14931 for PCs, but a Mobile build isn’t coming today.

The build, of course, includes some other minor fixes which should make the overall OS experience slightly better. Additionally, the build includes some known issues which you should always be aware of before installing the build, especially if you are planning to install it on your daily driver. Lastly, it is worth noting that the latest build introduces a single new feature — and that is native support for USB Audio 2.0.

Here’s what’s new, fixed and broken in this:

WHAT’S NEW

What’s new

Native support for USB Audio 2.0: We now have native support for USB Audio 2.0 devices with an inbox class driver! This is an early version of the driver that does not have all features enabled, for e.g.: only playback (render) is supported with this version. Recording (capture) support is scheduled to arrive in later iterations. We encourage you to play with the driver and let us know what you think (using the Feedback app). If you already have third party drivers for your USB Audio 2.0 device installed, follow instructions in this blog post to switch to using the inbox class driver.

WHAT’S FIXED

What’s fixed

• We fixed the issue causing people to experience a black screen when signing out and switching to another user account and unable to log in to that account.
• We fixed the issue causing the built-in Windows 10 apps such as Calculator, Alarms & Clock, and Voice Recorder to not work after updating to a new build.

WHAT’S BROKEN

What’s broken

• While using Narrator and Groove Music, if you navigate to the progress bar while a song is playing then Narrator will continually speak the progress of the song e.g. update with the current time of the progress bar every second. The result is you will be unable to listen to the song or hear any other control you navigate to.
• Oracle VM VirtualBox will crash on launch after upgrading to this build.
• Optional components may not work after upgrading to this build. To get it working again, go to “Turn Windows features on or off”, scroll down and check the right optional component and click ok.  After a reboot, the optional component will be enabled again.
• For keyboard users, using tab to navigate the Settings app will not work in this build. The arrow keys should work as a temporary workaround.
• Tencent apps and games will cause your PC to bugcheck (bluescreen).
