Hello,
I have new apple tv connected to a HDMI monitor that does not have its own remote that allow volume control. Is it possible to change the volume with siri remote somehow? I only saw that there is an option to learn a new remote but my monitor does not have a remote and I did not see any separate system volume setting in tvOS settings or anything similar. So I guess that it is not possible to change global tvOS volume in my case, right?
