i have 2 streaming stick+ that are doing this. it happened 2 days apart. first one quit, replaced the batteries, its started screaming and will not work. Then 2 days later, the other did the same. a bit upsetting, as these are fairly new devices that I now must replace. Ive not had the best track record with Roku devices, they seem to become problematic, as I have had to replace devices in the past due to glitches or lack of response.
I have had this issue multiple times already. I've bought about 4 remotes already and have ended up with the same issue after some time. Everytime i have purchased new batteries and each one will continue to make the same noise and will not work. Each remote that I've gotten will last me several months and then one day it will just stop working and start making the high pitch sound. Im currently experiencing this issue again and I'll probably have to buy yet another remote.
