I'm having the same issue with Transformers: Dark of the Moon 3D.
Strange thing is, at least in my case, the picture seems unaffected and it's only the audio that goes mute for a split second.
I recall having concluded that the problem only happened when streaming HD audio over HDMI and not when sending decoded PCM, but don't quote me on this.
If necessary I can confirm it.
