Yeah, maybe.

Between ourselves, historically, "scu" user was only me, and was used locally.
At one point, "simple-audio-card" had been handled both, but noticed that
it is impossible or will be super very complex.
Because I was the only user of "scu", it is separated.

"scu" is for DPCM, but is covering only one part.
It is not enough for generic use case...

Thank you for your help !!
Best regards
