Roku Ultra suddenly buzzing and crackling constantly
I've been using Roku Ultra with voice remote for over a year without any problems. However, for the past few days, I cannot use Roku at all due to very loud buzzing and crackling as soon as it powers up (although the video is fine and the remote works).
I don't use a soundbar. I have excellent speakers and AVR. I use Logitech Universal remote to control devices. I've verified that every mode other than Roku is working fine: TV and DVR, CD, Blu-ray, Sonos via my AVR, and radio, so this is not an amplifier problem as far as I can tell.
Could you try performing a factory reset on your Roku Ultra and see if that will resolve the issue you're experiencing? Feel free to follow the steps below to reset your player with your Roku remote or Roku mobile app:
Press Home on your Roku remote
Scroll and select Settings
Select Advanced system settings
Select Factory reset
If you have a Roku TV, select Factory reset everything. Otherwise, move to the next step.
We're sorry to hear about the issue you're experiencing.
We would recommend starting first with my suggestion above. If still no dice, please reply here with the serial number of your Roku Streambar. It can be found from the Settings menu by navigating to Settings > System > About.
