Hello. My unit is only a couple months old but every time we turn it on there is a very odd sound like an alarm but not an actual alarm. The unit needs to be turned off then back on and sometimes more than once. Then sometimes there is no sound at all no voices etc.
Can you please provide more information about the issue you are experiencing? Does the issue only occur on a specific channel or all channels on your Roku device? What troubleshooting steps have you taken so far to try to resolve the issue?
