Thanks for reaching out and I'm sorry to hear that you're having an issue with your Chromecast Voice Remote. Please try the additional steps listed below:
Let me know how it goes.
Hey there helpmeplease,
No problem, we can keep looking into this. You mentioned that the LED light is pulsing and not responding. This indicates that the remote is ready to pair, or that an attempted pairing was unsuccessful. Have you already attempted to factory reset the remote? What is the firmware version of the Chromecast? Are you able to use the virtual remote in the meantime?
I look forward to your response, and if you had any other question, please let us know.
Just checking in to make sure that you've seen our response. Please let us know if you still need help as we will be locking this in 24 hours if we won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
Thanks for the help, Jeran.
