Problems at trying to use multiple USB interfaces
I've recently tried to use my two audio interfaces at the same time to use four instead of two tracks for multitrack-recordings, but I didn't find a working solution.
This was the link I was visiting:
The first thing I tried was using those 'alsa_in' and 'alsa_out' tools. While Ardour was running, they weren't able to connect to a jack server, but in Qjackctl it worked fine. The problem is that Ardour isn't able to start while Qjackctl is running. It seems that it wants to start another jack server...
The other thing was the pseudo-device-setting in my ~/.asoundrc file, which hardly changed anything. Where should I be able to find my new pseudo-device?
