I am trying to make my new Nvidia shield tv control the volume on my new Linsar ls75uhdsm20 smart TV, so I only have 1 remote.
Both devices say they support hdmi-cec. Should hdmi-cec allow volume to be adjusted by the Shield? Do all the HDMI ports on the tv support CEC? How can I tell if my HDMI cable is the problem?
Thank you kind strangers!
I have an old Sony TV and do this with my shield.
I use the Sony remote to control the shield tv and it works great.
