Noah has bought a sound bar, but it won't turn on with his Google Assistant. Leo says if the sound bar isn't supported by Google, or vice versa, it won't be able to use voice activated control from the Google Assistant. He could just leave it on, but if it shuts down automatically, then that's going to be a problem. He should look to see if he can disable the eco, or power down mode.
Joe in the chatroom says that if the sound bar turns on automatically, then he can get a smart plug to plug his sound bar in. Then the Google Assistant can work with it. Another solution could be the Logitech Harmony Hub, which can work via infrared and is controllable by Google Assistant.
