I really hope one day Sonos will add YouTube for audio only as an added service. But the issue that I am having is by using my Line-In I get periodic cut outs / silence when music is playing. I have switched speakers for the line-in with the same results. I have also switched the channel to all three but again the same results. I have also tried using a PC, Tablet and Phone with the same issues. Does anyone have any thoughts or similar issues using the Line-In and cut outs?
