Every few minutes or so, the Realtek HD Audio Manager which sit in my icons tray spouts off this nonsense:
Sound cuts off for around ~1 second, and then...
The problem is, I'm not unplugging or re-plugging anything into any jack. My speakers are plugged into the rear port, as the always have been. Installing the latest drivers did not solve the issue. Disabling the front-panel detection (A popular "fix" for this problem) did nothing to solve it either, as this is a problem with the rear port, not the front panel.
This computer is literally brand new. I've had it less than two months.
