For the past month or so, whenever I play audio on my 13" rMBP the audio cuts out for about two seconds once every 30-60 minutes or so on average. Everything else keeps going - if I'm watching Netflix, it doesn't skip, if I'm listening to music on iTunes, it doesn't stop playing, the sound just completely cuts out. Sometimes it comes back on with a nasty, maximum volume buzzing sound. Anyone ever hear of this happening before? It's still covered under Applecare and I'll probably bring it in sometime in the next few weeks if I can't figure out a solution because it's pretty annoying when it happens.
