HDMI CEC Volume does not seem to work

Good Day,

I’ve been trying to set up the HDMI CEC on my Home Assistant installation on my RPi 3B, and is working for the most part. However I can’t control the volume using the hdmi_cec.volume or using raw commands.
But strangely enough, using echo "volup" | cec-client -s in the SSH shell works.

I don’t get any errors in the log whatsoever. So my question is if its the Components fault, my fault or my TV’s fault. Is there an alternative method other than the HDMI_CEC component or a way to fix this?
