"All" would suggest at any time, any channel would have these, but they don't, and I actually think reports of "all" channels, would hinder getting this resolved. If you can point them in the right direction, where they can see it, you're going to get much better results than pointing them to a channel that doesn't have them, where they conclude "you have" the problem with your system. What you seem to be asking DirecTV engineering to do is to have a person monitor each and every channel's audio. What I was trying to get in this thread, were common channels that have this most of the time, which we sort of got. ESPN, USA, TNT, to name a few. Monitoring these might be more productive.
