Yes, I know that it might be possible with two or more soundcards attached
to different chains, but how about doing it with one. With my delta 1010lt. I
heard, that someone had to open all channels at once, because the
alsaplugin-devices wouldn't work. Now I'm trying to figure out, how I can
attach inputs 1/2 to chain a1 and inputs 3/4 to chain a2. How exactly would
that be done? I think it won't be a good idea to do something like:
ecasound -a:a1 -f:16,10,44100 -i alsahw,0,0 -a:a2 -f:16,10,44100 -i
alsahw,0,0 -a:1 -f:16,2,44100 -o a.wav -a:2 -f:16,2,44100 -o b.wav
I think it simply doesn't work.
