What is the fix for this problem, I have tried replacing the batteries, repairing the remote, changing tv’s. Power on/off etc. the app remote on my iPad works just fine, it’s only the remote that doesn’t voice prompt feature that doesn’t work.
I have had this same issue for weeks. This is a Roku Ultra 4661. I have 2 identical model remotes pairs to this Roku. One works fine, the responds to all voice commands with "unable to hear you". I have tried re-pairing. No luck. The batteries show a charge of about 50%, but will try fresh pair and report back.
