Ripped CDs into WMA-Lossless from Zune software. This is interesting to me because my old Beyer DT770/80s did this when connected to this computer, no matter if it was the headphone jack, FiiO E7 fed by USB, or with E7 as DAC to my DV 337. Always did it when fed from this computer. I never noticed it form my desktop (this is my laptop). Could it be the software? I'll try VLC later.
