Force bluetooth headphones to connect with A2DP profile on WIndows



Bluetooth is a wireless technology that allows electronic devices to communicate with each other over short distances. It is commonly used for transferring data and audio between devices, such as headphones, speakers, and phones. However, many users have encountered problems when trying to connect their Bluetooth headphones to their Windows computer. Specifically, the audio will often be routed through the lower-quality HSP/HFP profile instead of the higher-quality A2DP profile. This article will explain how IT admins can force their Windows computer to use the A2DP profile for a Bluetooth headset.

The first step is to ensure that the Bluetooth headset is properly paired with the computer. On Windows, this can be done by going to the Control Panel, clicking on “Devices and Printers”, and selecting “Add a device”. Once the device is found, it should be paired by selecting it and clicking “Next”.

The next step is to check that the headset is using the A2DP profile. To do this, open the Control Panel again and click on “Hardware and Sound”. Under “Bluetooth”, select the device and click on “Properties”. In the “General” tab, the “Profile” field should show “Advanced Audio Distribution Profile (A2DP)”. If the headset is using the HSP/HFP profile, the “Profile” field must be changed manually.

To force the headset to use the A2DP profile, the IT admin must open the Registry Editor by typing “regedit” in the search bar and clicking “Yes” to the UAC prompt. Once the Registry Editor is open, the admin must navigate to the following key:

HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\BTHPORT\\Parameters\\Devices

This key contains sub-keys for all of the Bluetooth devices that have been paired to the computer. The admin must find the sub-key for their Bluetooth headset, then double-click on the “Cod” value and change it to “0x20041”. This will force the headset to use the A2DP profile.

Once the change has been made, the admin must restart their computer for it to take effect. After the computer has been restarted, the admin must check that the headset is using the A2DP profile by following the steps outlined above. If the profile has not changed, the admin must try unpairing and re-pairing the device.

In conclusion, it is possible for IT admins to force their Windows computer to use the A2DP profile for a Bluetooth headset. However, this requires manually editing the Windows registry and so must be done with care. If the admin is not comfortable with editing the registry, they should contact their IT support team for assistance.
