I'm well used to it by now. Most of the clicks come when a new lock is required on an audio signal I think. This is common when a broadcast transmission that might have been in DD moves to advertisements. If the soundtrack on those is a mixture of DD and PCM then there will be more clicks. I also see it frequently on DVD/BR discs in the various trailers/announcements before the feature starts.

I don't perceive it as a problem, but clearly some people find it annoying. There are plenty of processors that do it though.
