Re: [ecasound] Recording and monitoring

Hi Julien,

Before asking my question I read the tips you wrote about these
subject. Thanks for this work but I did not find any answer to
this particular question in them.

  Things might be easier but I suspect with less understanding
  of the process.Moreover I'd prefer not to install jack on my
  system if things might function without it.

  up to the syntax which is not completely correct :

  ecasound -a:1 -i alsa -o loop,1 -a:1,2 -i loop,1 -a:2 -o alsa
  -a:3 -o file.wav
  It works.

  In my opinion that's precisely the point were things are not
  completely clear : What correspondance between alsa hardware
  naming in ecasound and sound devices. If I get understand
  this point I'll try to write something. Anyway I suspect that
  it might be hardware dependent.
