i still have to run the tests but what i changed where the extra configurations
for the  dmix and dsnoop devices of the loop and the dsnoop at the hw1 end

this was what i added:

  ipc_key_add_uid true
  slave {
    pcm "hw:Loopback,0,0"
    format S32_LE
    rate {
      @func igetenv
      vars [ JACK_SAMPLE_RATE ]
      default 44100
    }
    period_size {
      @func igetenv
      vars [ JACK_PERIOD_SIZE ]
      default 1024
    }
    buffer_size 4096


furthermore i used jack 1.9.8 instead of 0.121.3

as soon as i'm done with the test i'll upload the log, do you need it with the
longer period or first the standard one?
