Hm. This illustrates that there is more than one opinion about the 
default. The problem here is that sometimes line-out is used as 
headphone-out.

Also "NuForce DAC-80" USB audio card that has a hardware volume control 
knob, and I found out that 100% hardware and 100% usb-mixer volume on 
that card is enough to overload analog inputs of a Final Sound FVSS 
201/Р receiver.

So, I think that the original plan with a 30% default on all analog 
outputs is better.

P.S. I do not own any of hardware mentioned in this email. It was only 
demonstrated to me by the salesman.
