I recently had a few problems with my computer that eventually resulted in me having to install a fresh copy of Windows. As I didn't get a Windows CD when I bought my computer, I had to buy a fresh copy. I'd been using Windows Vista on my laptop prior to the reinstall but when I found out I could get Windows 7 for the same price I decided to go for that instead.
Since installing it, however, my computer's audio has been very crackly. If I'm playing a file and now using the computer for anything else then it's usually okay, but even something as minor as scrolling through a web page brings out all sorts of crackles. After searching around Google for a solution it was recommended that I update my audio driver. I tried doing this through Control Panel, but the dialogue said I already had up-to-date drivers.
I'm running Windows 7 32bit on a computer with 2 2.16ghz processors and 2gb of RAM. My audio device is listed in dxdiag as a "High Definition Audio Device", and I have a HdAudio.sys driver dated 13/7/2009.
Any help would be appreciated.
