Chromecast with GoogleTV - CES does not work properly

by electrosam

Hi,
Chromecast with GoogleTV is connected to a TCL TV via HDMI.
The TV supports CEC.
In Android/Google TV setting CEC is enabled for power and volume.

The volume works in most cases, volume buttons on the remote control TV's volume. However if the Chromecast is turned off (with power button on Remote) and powered back on - The volume control stops working.

Additionally for Power CEC, chromecast turns off the TV when power button is pressed on the remote. However it does not turn it back on.

I think this could be happening if Chromecast is not broadcasting CEC signal for power and volume control post suspend/ sleep.
Is anyone having this issue?

Yeah CEC seems pretty broken. Luckily IR is pretty configurable but it does mean some Google Assistant commands won't work. It's definitely a Chromecast issue as the Shield works fine for me on the same TVs.

It is for this very reason that I hate anything cec related. Power and volume cec commands not working every time is very frustrating. After a decade and a half hdmi-cec is still not standardized as a technology and various manufacturers implement it as they see fit. By now you would think that it would be as reliable as ir, but it’s not nearly as reliable.

Same here its not powering the sound bar back on.

Xbox and PS4 all work correctly so I know its an issue with the Google TV. Hopefully they fix it soon.

Yea I've had my chromecast with google tv for about a month and CEC stopped working to the point that my girlfriend hates it and doesn't want to use the living tv anymore.

Is it a Roku TLC? I have a Roku TV and when I hit the power button on the Google TV remote it will turn but when I press power to turn it off the TV make the shutdown sound but then goes back to the Roku home screen. My theory is it sends the CEC power command but then turns of the HDMI output too soon which causes the TV to abort the shutdown and go back to the homescreen.

I like CEC in theory but there isn't enough control over any of it. For example on the Google TV if I could add a 3 sec delay between the power down command and the Google TV itself powering down then I think my issue would be solved.

I've the same issue using Sonos soundbar. Everything works fine but after turn off and turn on with the remote control (Google TV), the volume buttons stop working. The only way to active the volume buttons is restarting the Google TV device.

I also have a roku tcl tv and have the same issues you do. I did not remember having it before the last update.

To fix temporarily go into the settings and toggle off/on the CEC controls.
