Volume issues
 

When ever i alter the volume on winamp is alters my pc volume, for example i mute winamp and it will mute the volume if i check it in the taskbar, which is very annoying because i tend to turn winamp down when i want to quickly listen to something else on my pc.
This doesn't happen with Windows media player and i was wondering if there is anyway to fix it?
