"I have a headset with a USB sound card, and a normal, onboard sound card that is hooked up to speakers. I would like to use each of these sound cards at different times for different activities.
"For one thing, I like to listen to music. My desk is right next to my wife's; sometimes we feel like enjoying the same music, sometimes not. So I'd like to be able to switch my music player between my headphones and my speakers easily.
"I also like to make and receive calls via Voice-over-IP. I would prefer to use the headset to actually make the calls, but when a call comes in, as with a regular phone, I'd like to be able to hear it on my speakers until I make it to the desktop. Importantly I'd like to be able to do this even if I'm listening to music already. Without this requirement, I'd probably be fine with just one sound device. I'm beginning to wonder if it's worth the trouble."
