For the last week my sound has been going in and out. We have tried different channels and when the sound is out it is out. The only solution I have found is to reset the Roku device, sometimes this works and sometimes it doesn't. When the sound does come back it will go out again at random times till I reset the device again. In resetting I have done it through the system menu and unplugging it and doing a hard reset. What specific info do you need?
