I'm using Audioengine D1 USB DAC I was blaming the dac but some of the occurrences were no not happening using foobar, I'm not really interested in foobar, would like to take care of the problem. Also at first I thought it was lossless tracks but happens with mp3s too I'm using ASIO4ALL v2 Buffering set at 3.30 secs 24 bit
