If you have something like that, you<br>can make the output driver the default audio output device (all<br>programs sends to this device), and let jackd connect to the input<br>device. Maybe soundflower can do that, or maybe some other software.<br>You'll have to look around.<br><br><br> </div> </div> </blockquote></div> </div></body></html>
