A bit of research shows that this is most often caused by malware of some sort. I'd run a full scan with Malwarebytes and then, if the problem persists, ComboFix. The lack of rogue svchosts makes this a little less likely though. In the mean time, can I get the make and model of your computer? Could be something model-specific that will be easier to find with the right search terms. Driver updates for the audio hardware and any utility buttons on the computer may also help.
