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..
