Hi Heiner,

What do you mean „works without volume control“?

What parameters do I have to set in command line?
Or do I have to set maximum volume in squeezelite to not have any software component alter the stream?

Because then I’ll never know whether some player control will reduce the volume accidentally or by means and therefore will spill accurate transmission of digital sound data to the receiver.
