This problem first came up about five days ago, when I realised that one of my audio files wouldn't play. At first I thought it was iTunes (which I rarely use; at first I thought I was being reminded just why that was), but it turned out that I couldn't get sound to play at all. Moreover, I would get this message:
"Windows Audio Device Graph Isolation stopped working and was closed."
closely followed by:
"Windows Audio stopped working and was closed."
So I went into control panel to try and look at what was going on, and I got this message:
"Windows host process (rundll32) has stopped working."
Now the fact that my sound doesn't work at all is annoying enough. What is even more annoying is that I keep getting pop-ups from Windows saying "Windows Audio has stopped working" every thirty seconds! I'm not sure if it's a virus or not, but it's so irritating that I just assume it is anyway. But before I do decide to go all Rambo on my laptop, I want to see if it's a virus or just a hardware problem.
