Raymond,

It probably doesn't know. I suppose I'm losing the speaker (which isn't
connected nor used by me anyway).

On the other hand I'm getting a real Master as well as a Headphone switch,
Front, Surround, Center and LFE controls, and the channel mode. Everything's
working just great!

I have only a headphone mute switch, no headphone volume control, if that's
what you mean. But since the master affects headphone volume, that's OK.

What do you mean exactly? I have 6 channel output.

Thanks a lot. I'm understanding every single control now.
