Most computers have more then one usb port. And these usb ports sit on
different irq's, I doubt it that all of them are shared with the graphics.
How do you know which usb port uses which irq?
Check the output of "lsusb" and "cat /proc/interrupts" to see where you audio-
device is connected and which irq that port has.
Have fun,
