Hi
Thanks for the welcome
The TV info is
Sharp Model: 55GJ4x25K
Hardware ID: GE30X
serial number: X01900XN7UG0
SOftware Version: 14.1
The remote is
From Amazon
Manufacturer: Roku
ASIN: B0BMK9G6QV
Item model number: RCA1R
From TV:
Model: RC786
Firmware: rtn.4246
This was a new remote, purchased via Amazon. Your links do not work, but it has the reset button at the back of the remote, and the mic is under the on/off button. Similar to https://www.roku.com/en-gb/products/roku-streaming-stick-4k
I have reset the remote, then re-paired the remote with the TV (twice !) and it still has the same issues that the voice is not being sent to the TV. I got the message flash up on the bottom of the screen with the speech bubbles and examples of what to say ie Open Prime Video, SO the TV is "seeing" the remote as a voice remote.
All of the other buttons on the remote work fine, even the voice button is "seen" but I still see the message "Sorry, unable
to receive audio from your remote control. If this continues, try pairing your remote control again"
I am techy savvy and have been in the computer/network/electronics side of things for my career. So flashing firmware, etc does not pose a challenge.
Please can you help ?
Thanks
Keith
