i have raspi 2 , usb audio device (made pluggable). bought device cleaner audio out when using sonicpi.
few weeks ago working fine recent update has apparently broken sonicpi hangs on startup when using usb plugin.
here aplay list , tests speaker-test. default audio driver works fine, not usb. speaker-test returning error. i'm setting audio device via desktop (menu/preferences/audio device settings). appears pi @ least recognizing device.
pi@raspi2:~ $ aplay -l

alsa/pulse audio has tendency break every , then. has worked me when pulse/alsa stops working.
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
, force reload alsa again: sudo alsa force-reload
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
, force reload alsa again: sudo alsa force-reload
