Every time I reboot my computer the Control Panel -> Sound settings switch back to their default-install state. See the attached screen capture below. I can change the default Playback device to Speakers, and it works great. That is, until I reboot. Then the default Playback device is AMD HDMI Output again. This happens every time I reboot the computer. How can I fix it, so that the default Playback device doesn't get modified when I reboot? Thanks.
