Scenario: Your system was running fine, but you occasionally notice the sound output was "glitchy" and you decide to add a sound card. As luck would have it, a friend gave you his old sound card from a system he threw away. You install it, and the sound is great, except that whenever you try to download your songs at the same time you are playing them, either the download or the play stops or is intermittent. It seems worse than it was before you added the sound card. What would you do to troubleshoot this?
