Howdy. Switching from a Roku 4 to a Roku Ultra in our main media room. Already have an Ultra set up in the gym, works fine on a Sony 60 inch LED set. On the media room set-up, with a 4K 2016 Samsung 88 inch curved screen set, everything also went smoothly, except when setting up the remote. The system asked whether I could hear sound (which I could) and then asked whether the sound had stopped, which it had not. I was given the option to continue remote set-up, which I took. Now, however, on all content, I get brief but definite audio blips/drop-outs every few seconds, making everything basically unwatchable. Video is fine. Any ideas? Settings don't seem to allow me to address the issue, from what I can see....
