Atv2 losing sound while streaming netflix??

[Shanewilliams]

I watched 2 movies on netflix last night. Throughout both movies they would completely lose sound for 10-15 seconds at a time. The video stayed perfect though with no lag whatsoever. Does this sound like a glitch in the software or would it be possible to lose sound due to network issues? I've watched my atv everyday for about a week and haven't had any network issues at all. Any ideas??
