I recently purchased an HP Pavilion dv9925nr (for college mainly). At first it was really pretty amazing but as I began using it more often, I noticed a very irritating issue. As I play music, a scratchy noise will occasionally show up for a brief instant. It seems to happen about 2-3 times each song. This "scratchy" sound will occur through the laptop speakers, through my headphones, and even external speakers. At first it wasn't very noticeable, but now that I've heard it, it's driving me insane. As well, I have uninstalled and reinstalled and even updated the audio driver (conexant high definition smartaudio 221) but that didn't change anything either. It also seems to occur no matter what song I play, although some songs (seem to) bring the scratch more often than others.

Any advice or insight into this issue would be greatly appreciated. Otherwise, I'll be taking it back to Best Buy and demanding them to exchange it for a new one....

Thanks.
