audio enhancements, Bluetooth, AAC codec support and more

Microsoft has released version 21370 in the development channel on the Insider Program. A version that mainly focuses on correcting problems already encountered by users and therefore on improving the overall experience and final performance.

This compilation coming to Build 21364, introduces solutions that fix errors of all kinds and therefore, for example, errors that occurred while connecting Bluetooth devices are resolved, now offering better performance. In addition, the audio has been improved, supporting the AAC codec and allowing volume control on the headphones. Let’s see what improvements it introduces.

Audio enhancements and AAC codec support

The audio has been unified so that the voice and microphone of the Bluetooth headset now work correctly. Now only one audio connection point is displayed in the user interface and we will not have to click on different connected audio devices. Support for AAC codec is there, improving the quality of wireless audio transmission in Bluetooth headphones and speakers that support AAC codec.

Changes and Improvements

Some minor changes have been made to the icons in the File Explorer address bar. The touch keyboard launch animation has been improved to be smoother in cases where UWP apps readjust their flow when it appears. A change has been made so that if focus is set in the Run dialog box, the touch keyboard will now display a backslash ().
