How to Enable or Disable Bluetooth Absolute Volume in Windows 10

Windows 10 includes a special audio feature, Absolute Volume, that allows the volume slider to precisely control the local volume of your Bluetooth speakers (or headphones) connected to your computer. It is available starting in Windows 10 version 1803 'April 2018 Update'.

Microsoft is constantly improving the Bluetooth stack in Windows 10. For example, version 2004 of Windows 10 has got Bluetooth 5.1 certification, bringing all improvements of the latest stack version to users' hands. Also, Windows 10 is expected to get Bluetooth 5.2 features support in pre-release Insider Preview builds, to be included in the feature update coming after 20H1.

Absolute Volume is a useful feature. However, for certain Bluetooth devices it may prevent you from adjusting volume for the left and right channels individually. Once you change the volume level for one of the speakers, the volume level of the other one also changes automatically.

    Thanks so much. As a senior my hearing is not what it used to be. With Bluetooth headphones I need a little more volume in my left ear but that seemed no longer possible. Typical dumb move by M$. But your registry hack fixed it. Who was to know?

    I went through above topic and changed absolute volume because I needed Bluetooth speaker controlled directly from my laptop, but my bad luck since I changed sound itself is not coming from my speakers
