I have a roku streaming stick + that is powered by the external power supply and am experiencing static (snow) and audio crackles at the home screen and on any channel, until the device is rebooted - at which point it works fine. I have tried a new HDMI cable and various fixes from the forum, but the only thing that works is the reboot.
The device is 5 months old: is it worth returning it for replacement, or is there a proper fix for this?
Can you please clarify what you mean that you replaced with a new HDMI cable if you have a Roku Streaming Stick? Did you replace a HDMI extender? If so, are you able to connect the Roku Streaming Stick directly to the TV to see if you are experiencing the issue still?
