It sounds like the suspend or resume of power management introduces this problem. Probably you could reproduce this problem very soon just repeatedly suspend and resume the system.
cut in for all of 2 seconds or so (fairly consistent, that part), and then cut back out for anywhere from 10 seconds to a minute, then another 2 seconds of sound.. lather rinse repeat.
