No, it won't. You change the device you are using in the speakers tab of the option dialog. It is a lot better and more straightforward in media player 10 than 9. In the speakers tab, there should be a devices list. Gord ----- Original Message ----- From: A.

Sonar uses m-audio 1010lt, but all the other sounds are coming out of the one for Jaws. I like to be able to hear windows media player an winemp from the M-audio as well. Is it possible, if so how? If I get it work that way would it interfere with sonar and give me problems? Thanks Caglar
