Hello,

Thanks for your input Kuninori! Some questions first though :) On top of 
what Amadeo already highlighted, I'd like to understand what do the 
below three mean:

 >>     - fixed playback vs capture
 >>     - fixed CPU vs Codec
 >>     - DPCM connection vs normal connection

Especially the first two - what does 'fixed' stand here for?
