Told to turn off surround sound??? for popping noise

Our new Civic Touring had the intermittent popping noise like many others. I had it in twice for software updates. After the second update I was told to turn off the surround sound and only use it with USB items, not the radio. Honda said this was causing the popping noise. I researched the manual and online and found nothing. They first led me to believe this was a temp fix until they solved the problem. I was pushing for a new amp like others got. Now they say don't use the surround unless I use it with a USB item. How crazy is that? I can't live with this excuse. Anyone else told anything similar? Why have surround if you can't use it? The system doesn't sound nearly as good.
