Could you elaborate about "the audio goes in and out a lot"?
Is it that, while playing a video or sound, the audio gets in and out
permanently? Is the sound fading in/out or just straightly being cut
off?
Or is it the audio going off after a while or inactivity then being
difficult to turn on again? I'm thinking of the auto-mute, which can be
amazingly turned on and create unexpected behaviour (see alsamixer if
that features exists for your sound card and if it's ON).
