I saw something similar. Basically, it looks like the 501 actually STOPS optical output between channel changes (and when you pause also) -- as opposed to sending a no-sound/silence signal. So, this popping is likely caused by your receiver kicking back in after what it sees as a new source coming in.
On mine, I don't get a popping -- but my receiver takes about 3 seconds after an optical signal starts coming in to actually start outputting sound. So, if I pause and then un-pause, I get 3 seconds of video before the audio kicks on. This is so annoying that I've stopped using the optical out from Dish for now.
Basically, they need to output silence via the optical out when changing channels and pausing -- there should be a signal all the time basically when the unit is on -- regardless of what you are doing... Maybe they can work this into a software upgrade.
