KB5034204 finally fixes this Bluetooth Low Energy (LE) Audio issue on Windows 11

Big week for Windows Insiders, as Microsoft just released the Windows 11 Insider Preview Build 23615 which adds USB 80Gbps support to Windows 11, and Build 22635.3061 (KB5034215) to the Beta Channel, which brings a new lock screen experience to Windows 11 users: a richer weather forecast.

However, the Redmond-based tech giant didn’t stop here: the company released Builds 22621.3078 and 22631.3078 (KB5034204) to Insiders in the Release Preview Channel on Windows 11. The packages adds a couple of new features, but it also comes with a lot of fixes.

One of them finally solves the Bluetooth Low Energy (LE) Audio issue that has been affecting earbuds, causing them to lose sound when streaming music.

The annoying issue has been finally fixed in the Beta Channel, meaning all Windows 11 users will be able to properly enjoy this recently added technology. Bluetooth Low Energy (LE) Audio has been on the market for a while, but Microsoft only released it to Windows in 2023.

The technology is superior to the standard Bluetooth connectivity, as it makes Bluetooth connections consume less energy, thus extending battery life.

Below you can see all the changes and improvements coming with KB5034204.
