HDMI-CEC is enabled on my tv. I have two devices - Stb and the Chromecast.

Till a couple of days ago, I didn't need to tap the input button on the Chromecast remote to switch to the input for Google TV. You tap home, YouTube anything and it'd switch. It's helpful as input button is IR based, while the rest are not so you don't need to point to change input.

This has suddenly stopped working. Meaning if I do the above it won't work and similarly if I switch on the tv using Chromecast remote and a different input was selected, it won't auto switch to Chromecast input.

Doesn't seem to a problem with the tv as the STB pressing any button switches to the STB input.

I tried updating Chromecast, restarting it, remapping buttons, just doesn't work anymore : any tips guys?
