I'm having issues playing 24/88.2 files on my macbook pro. Whether letting decibel control the output resolution of my music streamer II, or if I change the settings in Audio/Midi setup and listen with iTunes I'm experiencing the same effect. Eventually a little crackling then the track goes silent. I've had said issue with Flac and Aiff. 16/44.1 plays fine, as does 24/96. I don't know if I just need more ram, I have 2gigs right now, but I would think this would happen at 24/96, or with any larger files if that were the case. I'm lost.
