I recently bought a Sony Smart TV that comes with Google TV. Before this I was using an older TV with a Google Chromecast TV dongle that had the remote. I was able to set it up to control my Vizio soundbar which worked great. The Sony remote does not have this option. I tried to pair the Chromecast remote to the sony which worked, but then it didn't have the options to set up controlling the soundbar and the previous setup does not seem to work if the dongle is off.

I tried continuing to use the Chromecast, but the sony randomly switches back to the wrong input. Is there an alternative remote I can pair with Android TV that I could set up to control my soundbar?
