StephenCharles 0 Report post Posted September 27, 2017 USB to RCA sound - Is it possible? Hi All, I recently purchased an ATV 1900Pro. My surround sound system is dated, and it doesn't have a SPDIF input, it only has analog RCA inputs. My question is - is the box capable of running sound via one of the USB ports? If so, I could possibly run the sound via a USB to RCA cable. Don't really want to go the route of purchasing a digital to analog converter along with all the cables required. Any assistance would be greatly appreciated. Share this post Link to post Share on other sites
