Hi, thanks for this useful article. It is something that I don't get. In the asoundrc example file, I can read "They have been split into top row and bottom row with channels 0-7+16-25 on rme9652_0 and channels 8-15+26-27 on rme9652_1." But it is no channel numbered 26 or 27 into this asoudrc.
If I understand well the code into the file, both sound cards are using the same stereo channels 24 and 25. And we have 27 bindings for 25 channels.
