Speaker problem long term but consistent
I have dell Ultrabook laptop with good built in speakers. I used it very rarely and nowadays I have found a problem. Over a time I have found that the problem is repeatable. Straight to the point. When I start laptop and do not play any music for 20 minutes or more, I have to forget speakers in the laptop. If I play any video, only the video plays, but not its audio. But, if I start the laptop and play music immediately, then there won’t be any problem and I can hear to audio while checking video too. Hope i am clear with my question. Please let me know any solution if exists. Please do reply.
