its going on a year now and the cable company cant fix the problem. on cable channels (not network stations like abc, nbc)i get a loud popping sound....but only during locally inserted commercials. the national commercials play then the local commercials are inserted.....thats when the popping sound occurs. all 4 tv sets do it.

any ideas what could cause this?

RE: cable tv/popping sound on locally inserted commercials

Is the pop sound just a one-off when the local commercials start? If it is what I think it is, it's nothing to do with your sets or setups, but at the cable network where they do the 'switching' - generally if they're working with a live feed from the cable broadcaster, somebody has to throw a switch to the local ads - the machine for this is usually called a vision switcher but I suspect sometimes these outfits use pretty ropey devices and it's just the result of a bad setup - and audio is worst, if you switch hard from one source to another without some sort of cross-fade, you will pretty much ALWAYS get a popping sound. Reason why the networks don't do it is all their stuff is configured and managed correctly.
