HELP USB to DAC = Loud Bursts of Volume

Okay, I have a Macbook Pro and a Bel Canto Dac 3. I have gotten intermittent loud bursts of volume when I am connected via USB. This has happened 3 times at least in the last month. The volume setting on my Dac/Pre has not budged and I have no idea what is causing this. It just all of sudden goes to like MAX volume. I quickly turn the amp off or unplug the usb to avoid damage to my speakers.

I have never had this problem when I stream wirelessly from Airport Express to the Bel Canto's optical input.

Anyone have any idea what is going on? I called Bel Canto and they have never heard of such.

It has only happened when connected via USB and while music was playing. Once you mentioned static a light went off. I am sure that at least two of the times this has happened, it was as I touched the MB Pro, and I distinctly remember static electricity. I immediately killed the music because I was concerned for my speakers.

It makes perfect sense to me now, because before I upgraded to the Pro, I had a Macbook for a few weeks. The issue never happened as the Macbook uses plastic casing.

I will call Bel Canto again tomorrow and ask for Matt and I will make sure to mention that I am not the only one having this problem. Hopefully they can resolve this issue. I have resulted to using the Airport Express again, not that it sounds bad, but I prefer the USB set-up since the general consensus is that is sounds better than using the AE.
