The sound in my 1.5 year old laptop suddenly stopped working. Before it stopped it made the normal "trrrrrllllll" (ad infinitum) sound it makes when it freezes. This happened after I had restarted the computer when I realised that there was no sound. I don't even know what started it. I was using the chrome browser.
I raised the volume and open "Jack" from the control panel but nothing happened.
Please don't suggest I download the driver from the website. Six months ago my camera stopped working and i kept downloading the camera driver from the website but it didn't help fix my problem. I don't want this to happen to the sound too, downloading the driver would mean that there is no hope for the problem to fix itself.

The funny thing is that the sound plays when I shut down the computer..wtf?
