Umm I dont know how to explain this.... There is a limit for the number of applications that play some kind of sound at the same time. For example on my old comp if I was playing music I couldnt hear any other sounds from any other programs becuase my sound card could only play one sound at a time....
There is a place in windows where you can specify/limit this number, I cant find it.... anyone can help?

sorry for the poor explanation
