Is that the same 'every' that have wireless speakers or 'soundbars'?

Because I'm pretty sure mine doesn't. I hate it, I'm the first to point it out or only one bothered by it. I haven't done anything (other than run Audyssey) to stop it, it just hasn't been a problem as far as I can tell.

And I know you're exaggerating, anyone would notice 'hundreds of milliseconds', but still.
