Just from last night, the audio jack started behaving strangely. A pop up from the tray icon will say "You just plugged a device into the audio jack." and then shortly after, "A device has been unplugged from the audio jack." The process is repeated until I restart the computer. But, I'm not plugging/unplugging things in to the audio jack.
I thought it may be the Windows 7 update caused it, so I did a system restore, not working.
Uninstall the software installed yesterday, not working.
Dell Diagnostic tool used, passed...
Any other idea that may solve this? Don't want to replace the mother board... ;(
