I found what the problem was...

It seem that when you plug the USBStreamer B for the first time the
asound.state does not have any channel mapping so it creates one for the
first time and read it the next time when the computer boot and alsa
start.

I erase the information of USBStreamer on asound.state, reload alsa and
I worked.

Title:
  [USB-Audio - USBStreamer, playback] No sound at all

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  USBStreamer worked fine the first time I connected it to my Bodhi
  Linux computer 8 channels in, 8 channels out connected to a Yamaha 03d
  with the adat expansion card.

  Next day I tried again and nothing no input, no output. Alsamixer only
  recognize TWO controls: master playback and master capture, unmute
  master and check on capture did nothing.

  I decided to test with a windows computer and USBStreamer B works
  perfect so I did a fresh Ubuntu Mate 15.10 installation to my
  computer. Once I finished to install everything (JACK, etc) I plugged
  the USBStreamer B to the computer and It worked perfect 8 channels IN
  8 channels OUT..

  But next day the same thing NO SOUND IN-NO SOUND OUT. But now I
  unmuted alsamixer Master PLAY and checked CAPTURE and only got
  CAPTURE, NO PLAY.

  If I plug the USBStreamer B for the first time it works perfect, but
  after that It doesn't..
