回答“My headphones don't work when I plug it into the jack?”I'm having the same problem. I have a Dell laptop and so I've been taking with the reps. They gave me links to reinstall and I'm still having the same problem. The install links I got were: chip set, bios and the audio driver. I tried different headphones with no luck. I've looked online for a fix. One actually worked but it was only temporary. I'm wondering if my bluetooth devices are part of the problem even though they were never an issue before. I've never had this problem before and this one is a complete mystery. Even the reps at Dell are stumped. Their solution is to do a mail-in service.
