No volume controle

Is it normal that there is no posibility to adjust the volume with the aluminium apple remote?

 

 

Yes.

One is expected to control the volume on the device that is driving the speakers.  Depending on your setup this is likely to be the TV itself, or perhaps an AV amp.

Why not controlling the output volume via the remote???  There are unused Up and Down buttons on the remote (At this stage the up button shows the timeline…unuseful feature I think)
