Just thought of something, the auto-detect of devices plugged into my audio ports goes off whenever I plug something into the jacks. If it was faulty would it still detect devices?
Depends on exactly what failed if something did fail.
If you are playing audio/video and trying to find which jack sound is going to, you might need to restart your player or at least stop/restart playback to make it pick up the new connection. This is another thing that contributes to my frustration with port re-tasking, wish I could turn that off.
