Topic: Casading of two RME Digifaces in order to record 48 tracks simultan


I want cascade my two RME Digifabes in order to record 48 tracks simultaneous. I synchronize the two Digifaces via Wordclock.

Operating System: Ubuntu Studio 15.10 Wily Werewolf, 64-bit version

DAW: Ardour 4

The HDSP control-Software and the HDSP-Mixer works very well, I can see both Digifaces and have access. I can do the settings on the Digifaces.

But I can't see the second Digiface in Ardour, when I select the Inputs. I see only the first Digiface with the 24 Inputs and Input 25 and 26 (Spdif Stereo).

I have read about the .asoundrc-file in order to aggregate the twao Digifaces to a big "double-digiface". I have make so a .asoundrc-file, you can further down
but it don't work. I cant see the second Digiface in Ardor and in Jack-Control.

I have copied by root-rights this file in the home-directory of the audio-user.

After this expierience of no-function, I hafe remove this file from the computer.

I'm not ao programmer or software-engeneer, who can help me in oder to reach the aim to cascade the two digifaces in order to record 48 tracks.

Here the .asoundrc-file, what is wrong ?

Or I neet an other solution for this problem?

In my opinion have the impression, this is a software-problem.

Kind Regards
