Playing music with Winamp as input device and using mic

[sparkSy]

Hi, i have a problem. When i am shoutcasting and playing a song I have to use Winamp as input device which is fair enough. But when i talk i have to change Input Device to Soundcard input.. This makes everything very hard and takes alot of time, and the music end very quickly as i change.. How do i talk and play music with the same device?
