I just build this computer over the summer and about 3 months ago the volume started jumping up and down for no reason. It is absolutely maddening. At first I thought it was just Spotify, but now I'm seeing it happen with everything. I've reinstalled the driver and disabled audio enhancements and there have been several Windows updates since the problem started. I don't know what else to try. It is driving me bananas. Has anyone else had and resolved this issue?
