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?
I've experienced similar, but not exactly this.
How long before the whole motherboard dies?
Whoaaaaa, don't get ahead of yourself. My current mobo has had a bad audio jack for 3 years and the mobo still works fine. So the answer could be that the motherboard lives another 40 years. Your first step is to follow the suggestion of Don Tai. Put electronics lubricant on your headphone plug, push it in and pull it out about 40 times, and see if the symptom changes. Do this with each headphone. If the symptom goes away, Merry Christmas. If not, you've at least learned it's not simple fretting corrosion. You can get USB sound cards of all price ranges and qualities. If you're going to do recording, I suggest at least 24 bit. I replaced my computer's defective sound card with a $20.00 USB sound card, and have been happy ever since. In another message you said you're getting the same symptom with the rear "line-out". A line-out can't drive a headphone: It doesn't have the current. Perhaps it's a rear speaker jack? SteveT Steve Litt http://444domains.com
