I have a Acer laptop, and my speakers have stopped working. about 3 days ago I was listening to some music and my speakers got really staticy......the static calmed down after 30 min or so and then they worked fine. Now they have stopped working all together. I cant even get sound when I plug my head phones in. I have checked all of the volume levels and everything is normal. I even ran a scan to see if it cound diagnose the problem and everything came back "no issue to diagnose". is there anything I can do?
