I'm having the same problem.
Setpoint 4.0L (says 4.60.122 in Setpoint though)
Closed Setpoint in Task Manager and volume adjust works, with Setpoint running volume adjust does not work.
With all other sound devices disabled volume adjust works. With other sound devices enabled volume adjust does not work. I cannot disable all other sound devices because I use two sound devices. This is a real pain. I expect this mouse to perform all of its stated functions.
