I just got an SMSL M2 USB DAC. I have the output plugged into my SMSL sAp II headphone amp. In Foolbar200 I have WASAPI set, but I get popping/clicking noise when I click on a track to play and also when clicking play, pause and stop. What could cause this to happen? UPDATE: Just installed ASIO4ALL and now I only get a pop when clicking a track, play and pause.
