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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1526569 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..
