Headphone not detected in new computer

Hello,

There are many reasons your headphones might not work on your system.

One of the problems might be that you might have uninstalled the sound card device driver software from your System which would show a cross mark on your volume icon in the tray pane.

Other problem might be that you might have installed an update of sound card driver which might not support the proper function of these headphones.

Last but not the least problem might be of the corruption of the driver supporting the sound card and microphone input of your System.

Do check these out and you will definitely find out the solution to your problem.

Where did you plug in your headphone? If you plug your headphone in at the rear jacks of your sound card, does it work? Does it work if you plug it in the front panel? Does your motherboard or sound card have HD (high definition) audio or does it have AC '97 audio?

You didn't say where you plugged it in but I assume for now that you plugged it into your CPU chassis front panel audio jack. I am also assuming that your motherboard has HD audio.

Most computer cases have built-in front panel audio jacks. However, those front panel jacks are commonly for AC'97 audio. New motherboards on the other hand usually have onboard sound and have HD audio. One crucial difference between AC'97 and HD audio is the location of the "sense" pin.

This pin is what tells the sound card that an audio device (such as a headphone) has been plugged in. If the sound card, does not detect the insertion of a headphone, it will not switch the sound output from the rear to the front which is why the sound still comes out of the speakers instead of the headphone.

For your headphone to work, you should plug it in to the rear audio jack (green color coded jack).

If you have Realtek audio, just follow the settings in the screenshot below.

If you want to use a headphone on your computer, first, check that the sound card is installed properly. Try connecting a normal speaker on your computer then play a video or music. See if you hear a sound. If you hear a sound, try connecting your headphone again then see if it works. Also, make sure you connect the headphone jack to the correct audio port.

The sound card normally has three ports: audio in, audio out, and mic. But sometimes it has four ports. Now, when connecting your headphone to the sound card port, you should insert the jack to the audio out port. This is the same when connecting normal speakers. If this doesn’t work and your headphone still can’t be detected, there is probably something wrong with the audio out port.

Try using a different sound card if the problem is with the sound port.
