What’s new in version 21370

Bluetooth audio experience improvements

Over the past few months, we have seen new features added to make Bluetooth audio streaming easier, better, and with better performance.

Unified Audio: No more clicking multiple audio devices for your Bluetooth headset’s voice and microphone to work properly. Now only one audio connection point is displayed in the user interface and it will be automatically replaced with the correct one for a seamless experience. Are you listening to Spotify and then having to enter a team call? Now we can also directly control the volume of the headphones.
AAC Codec Support: Enjoy premium wireless audio streaming quality to your Bluetooth headphones and speakers with the AAC codec. It is a lossless codec that provides high quality audio streaming in smaller files, ideal for listening to music.

We are working on a fix for WSL users who experienced a slowdown in File Explorer startup time after upgrading to Build 21354 or later.
