Tried a 12v psu and the same thing happened...Could it be a software problem?
Thanks,

What could be happening is during a peak load, the voltage is dropping below the 10 or 11 volts needed to run the output amplifiers and cause a cutout of sound. Don't invest in a new supply yet, just borrow one for the correct voltage, current and plug polarity. There are actually plenty of 12volt 1amp supplies on EBay for less than 10 dollars when you are sure....
