If both of these options aren't the cause of the problem, then its very possible that the audio is faulty and will need to be replaced. For a helpful guide on ways to fix these problems go to https://www.youtube.com/watch?v=9m0uISPA....

Hi, Just a few suggestions.

When it doesn't work what have you checked?

Have you plugged in headphones when this occurs to see if it is a speaker problem or not?

Have you checked in Device Manager to see if there is a problem with the Audio Controller?

Does it only occur when playing certain file types e.g. .mp3, .wav etc.?
