I've got a Ultra 4800 and now I'm only getting Surround Sound on my amp. I tested it in 4+ apps with the same result. Even swapped out the HDMI cable. Using VUDU on my Samsung Blu-Ray I get ATMOS but the ROKU and VUDU I only get surround sound. It was working before. Did ROKU roll out an unfortunate update?
