I'm curious as to why my audio is affected when certain programs are launched, even though I'm not using onboard audio. I bought a sound card to alleviate this problem, but something must either be malconfigured and/or unknown to me as to how to correct this condition.

Any ideas, anyone?

I'm using Windows XP Pro.
