Windows 10 21H2 comes with new features for Bluetooth audio

Windows 10 Bluetooth upgrade

Windows 10 has been criticized in the past for limited controls
for audio devices, with users regularly reporting issues when
using their Bluetooth devices for both voice and mic. There
have also been complaints about the audio quality itself,
especially when using premium products like Apple Airpods.

With Windows 10 Sun Valley Update, otherwise known as version
21H2, it seems Microsoft is doing more work to improve the
Bluetooth audio experience. For example, Microsoft is adding
support for AAC Bluetooth audio codec for all devices in
Windows 10 version 21H2.

In the latest preview builds, we’ve seen at least two big
changes. The first new feature is a unified audio endpoint,
which means your Bluetooth headset’s voice and mic will finally
work properly without switching between the two endpoints
(voice and mic) manually.

After the feature update, you will only see one audio endpoint
when you click on the audio icon pinned to the taskbar. This
means you don’t have to click through multiple audio endpoints
to use voice and mic at the same time. To facilitate this
feature, Microsoft will automatically switch to the correct
audio endpoint.

For example, Windows will automatically switch to voice
endpoint when you’re listening to music in Spotify. If you
switch to Zoom and Teams, the audio endpoint focus will shift
to the mic.

Windows 10 gets Bluetooth AAC codec support

For those unaware, Bluetooth codec is a feature that determines
how the audio files are transmitted from your computer to
headphones. A codec is required for encoding and decoding audio
files, and it also ensures that audio plays via the wireless
connection at the minimum bit rate.

With Windows 10 21H2, Microsoft is adding the AAC Bluetooth
audio codec to all supported hardware. Granted, this doesn’t
mean that it will work with every device running a new version
of Windows 10, but it should at least help users with a
compatible device.

The advanced audio coding
(AAC) is a power-hungry code and it enables support for
premium audio streaming. The codec supports lossy digital audio
compression and it is Apple’s preferred mode of transfer. As a
result, you can expect audio quality improvements when
listening to music online via Airpods and other AAC-supported

In addition, Microsoft also seems to be testing
additional improvements for File Explorer’s brand new

It is important to remember that all of these features are
still under testing in the preview builds of Windows 10 21H2.
Knowing how Microsoft has handled the rollout of these beta
features in the past, it’s going to be a while before they roll
out in production.

As per reports, Windows 10’s next big update is currently
expected to ship in October or November.
