I have an older Compaq Evo that recently started breaking up the sound. The video is fine. The sound is embedded, no card. When I watch a video, the sound will intermittently break for a second or two. Everything looks ok in device manager. This PC has XP. Cannot seem to find the driver either. Then again, I'm not sure if I'm looking for the driver I need. How do I make sure what driver I need? Also, if needed, could I install a sound card to resolve the problem? What do you think?
