Q: I am using a USB audio interface with my Apple Laptop.  Sometimes I hear a loud buzzing sound that also gets recorded, or I notice audio dropouts when recording or playing back; what can I do about this?

A: Under part 15 of FCC regulations, your M-Audio device “must accept any interference that may cause undesired operation".  In this case, your M-Audio device is accepting interference from the Bluetooth feature or airport wireless card.  To alleviate this problem, try moving your M-Audio device a short distance away from your computer.  Another solution is to turn off Bluetooth and your wireless network and / or airport card during the recording.  If you have a cell phone, move it away from your speakers and M-Audio interface.
