If I select Player instead of Perfect Wave DAC in the Playing menu, the files play fine through my laptop speakers without stopping, or any other defects in playback. The playlist will repeat and keep playing. When I try it through the DAC, it only plays from about 30 seconds to 1 minute and 15 or 20 seconds and it stops playing. If I play another track, it starts to play for the brief time and then it stops.
After playback through the DAC stops, the displayed time stalls at that point. If it stops at 54 seconds, the numbers change from 54, 55, 56, 57, then back to 54, 55, etc. The graphic play bar is stopped, and no sound is played.
