Can someone please help me!! I bought a Vizio and a Roku Express 2 days ago and when I'm trying to watch anything using the Roku the audio is lagging. I've read similar issues on here and tried using their suggestions but nothing is working. I switched out the HDMI cable that came with the Roku with one I already had and that seemed to fix the issue for a while but now its happening again. I'm beyond frustrated and of course cannot get ahold of customer support.
