if I am assuming something then it is because you have not provided sufficient information. Note that saying your PC clock is always within 100 ms of UTC doesn't tell me you are running a full NTP implementation. What is sure is that a step adjustment to the PC clock during a receive period will cause an audio stream discontinuity, and that in turn may disrupt all decoding for that period. You asked what might be the cause of occasional failures to decode any signals, I offered one common reason. If that is not the case for you then you need to look for other causes, audio discontinuities are still likely to be the cause so perhaps some peak of CPU or interrupt loading is disrupting smooth audio streaming.
