What should I do if the headphone jack on the front of the computer case cannot be used?

Q: The headphone jack on the back of my computer has sound, it can be used normally, but the front headphone jack can't be used. There is no sound when plugging in the earphone. It feels convenient to plug in the front of the headphone. Trouble, how can I solve this problem?

A: There used to be a netizen. Her computer is a win7 system. As with the situation you encountered, she solved this problem. Open “Control Panel”, find “Realtek High Definition Audio Manager” and open, open the “Jack Settings” folder, the “Encryption Settings” dialog box will appear, “will be disabled” Panel jacks & rdquo; detection can be ticked.
