loud "alarm" sound from roku box or remote
I purchased a Roku Streambar 9102R on 11/25/20 and it has been working fine. Last night I turned off the TV and Roku to go to bed and as I was walking upstairs this loudest alarm sound started blaring through the house. I couldn't tell where it was coming from at first. I initially thought it was my house alarm going off and was expecting the police to come, it was extremely loud. After 5 minutes I discovered it was coming from the Streambar and I had to unplug it to turn it off. I plugged it back in tonight and it seems to be working fine but I am fearful it will happen again, in the middle of the night and wake up everyone so I am unplugging before I go to bed. The model# and SN# is below. What could have caused this and how can I be sure it won't happen again?
