The problem is rather that it cannot handle loud *input*.  With loud
input from digital plus the respective DXS lever on high volume, it
apparently overdrives at a very early stage in the sound card.  Master
and PCM do not help anything any more.

The other workaround would probably be using softvol for reducing the
volume before it enters analog, but lowering the DXS levers is still
better IMHO.

Thank you
