Hi: very easy to do that. after installing the drivers of the sound cards, you do the following. go to control panel then sound&audio devices control tab to the audio page. choose your internal soundcard as the default play back press apply & OK you are done. in Sonar you choose the M-audio sound card from there. thanks William ----- Original Message ----- From: A.
