How do I stream Android audio to Windows 10 over bluetooth?

Solution 1:

• First, make sure your Bluetooth adapter is capable of "A2DP" audio streaming and that you set up the full/all drivers, not only the ones for peer-to-peer services.
  • Right click on Bluetooth > Options / Settings > COM Ports and check if your streaming service is installed there.
• Second, let Windows set up the drivers for your device. Just connect your phone to your PC through USB and wait for Windows to finish installing them. You should get some kind of notification once that's done.
• Last thing, set up your Android's sync program. You can most likely get that from the manufacturer's website.

Last note: You could also stream over WiFi too. Connect your phone and PC to the same network and get one of the countless apps from the app store that lets you stream media to the network, it's easier :)

Solution 2:

In Windows 10 versions released before Windows 10 May 2020 Update, Microsoft had implemented support for the A2DP source role, but not for the SINK role for desktop editions. This means you could use Intel Bluetooth on Windows 10 to send audio to other Bluetooth devices, such as a speaker, but you wasn’t be able to receive audio from other Bluetooth devices via A2DP.

Starting in Windows 10 version 2004, Microsoft has re-added the SINK role to Windows 10 for upcoming versions of the OS. However, to use the feature, you need to install a third party app Bluetooth Audio Receiver from Microsoft Store, as the OS lacks the user interface to activate the SINK role. This app should be running to be able to stream audio from Android to Windows 10 speakers over Bluetooth.
