Note: This is a workaround, not a root-cause fix. It disables hardware volume control for Bluetooth devices rather than resolving the underlying volume-mapping bug. If a proper upstream fix lands (kernel or WirePlumber), this page will be updated.
- After updating to kernel
7.1.3-200(or similar), Bluetooth speaker volume control stops working correctly. - The volume slider (KDE Plasma, GNOME, or other DE) moves visually, but has no effect on the actual output volume of the connected Bluetooth speaker.
- Can result in the speaker playing at full/maximum volume regardless of the slider position — potentially very loud/startling on reboot.
