I've been trying to play 16/44 with no upsampling or buffering, for several hours today. After about an hour the volume became very low and sound was garbled (not the typical loud static hiss issue though). Pausing/playing/track advance on LMS had no impact. I tuned the dac off and back on and poof, sound back to normal. Who knows for how long though. I'm starting to think that the "iec958:CARD=SA8005,DEV=0" output device setting just doesn't play nice with the dac.
