Yeah my roku is so annoying. I had to stop using it bc of the constant static and popping. I tried everything and it doesn't matter. I immediately just used my trash internal Chromecast again inside of my vizio. Don't get me wrong Chromecast is great all by itself but the built-in ones (under my usage) are always spotty for connecting. I have to continuously soft reset my tv in order for wifi and apps to pick it up again to connect. That's why I went and started using my roku again. Which at the time I got bc Amazon wasn't allowing casting, so I got my roku. There was no popping or static until i started using it as my main source for streaming. So I'm done with it. I'm going to check my warranty but it seems like it's a huge issue no matter what. So I'm not even bothering upgrading to the 4K one bc of it.
Same annoyance with my Roku 3. All solutions mentioned here work only for a few days - then the
crackle comes back. Can we expect a decent reply from customer support?
I took batteries out of remote for a night, next day put batteries back in and did system reboot, it’s been OK now for Six weeks. For me, if you have done this and still doesn’t work then Id try another Roku as they aren’t expensive, perhaps then I’d get another product. Could be that your TV somehow screws the ROKU device somehow. Just guessing, as seems most have done here.
What I did last week didn't work, I even put the Roku box further away from the TV set. When I start watching TV with my earphone everything is fine for about 10 minutes. Then all of a sudden the noise is popping up. It sounds like distorted audio - but not in the earphone. It comes from the TV's loudspeakers. I then run a powercycle, and the noise doesn't come back. I hope, that I don't have to powercycle whenever I start watching TV with the earphone.
Two nights ago the static was back, again! I was able to follow the steps I listed earlier, fixed it again. Just a guess, but whatever fixed the noise once will probably fix it again - whether adjusting audio settings, powering on/off, messing with the HDMI cable, etc. I have a feeling I'll be going through "my" steps periodically as long as I have this unit. Good luck everyone.
