yes, I was also going to suggest software as well. Can you try a USB headset, and do the same test? As for a bad audio jack, it is also possible that the soldered electrical contacts have cracked with age. You could, if you can, reheat the audio jack contacts with a soldering iron and remelt them. They should be quite large and easy to access, but you'll need to crack open your computer and motherboard, which is a pain.

Not sure if I misread the situation. But have you ruled out a software issue? Maybe some inadvertent change to your configuration. Try booting from a USB to see if same behavior.

I first noticed when viewing YouTube. So, I tried "audio test" from System Setting (KDE here). You get a popup, with "front left" and "front right" buttons. And, sure enough, depending on headphone, only mono was coming out, left side only, right side only, or to both sides.

William May I ask what is providing the audio for you? Before suggesting some possible causes, I would appreciate a better picture of your setup. Karen

I'm using 3.5mm jack, not USB. I don't think any internal contact is broken, because it's the same via front "headphone" or rear "line-out".

Do you use an audio jack or USB? If an audio jack, it is possible that the contacts are dirty and need cleaning. You can try a little electrical contact cleaner. But this should not affect the stereo/mono settings.

My audio used to work properly in stereo. All of sudden, it stopped working in stereo. Depending on headphones, - only 1 side has sound, or - both sides have sound, but it's mono (ie. same sound on both side).
Anyone experienced this? How long before the whole motherboard dies? ------------------------------------ Description: GTALUG Talk Unsubscribe via Talk-unsubscribe@lists.gtalug.org Start a new thread: talk@lists.gtalug.org This message archived at
