Many posts on hear about remote voice search issues.
I have A Gen 1 voice remote (AAA batteries and no headphone jack).
Used voice search button years no issue. Suddenly it gives a pop-up on screen saying "Unable to hear you. Try again"
These are external HDMI Roku sticks.
I've done all the suggested fixes from the community... rebooted the sticks, removed remote batteries, re-paired remote, etc.
I even paired the problem remote to my other roku stick on a downstairs TV and it still didnt work (the other remote worked on that stick/TV).
So it is not the stick or TV or software (one is a 3810 and the other a 3820) and they are on different TVs yet the problem persisted with that remote when pairing to other unit.
The Mic looks clean. I tried different voices, different speaking volumes, different search command phrases.
So it is the remote mic? Just stopped working?
