The fact that there is a snd_usb_audio is suspicious.  It looks like
alsa is treating a usb device as a sound device, when it isn't.  But
it is being placed in the first slot, 0, which everything assumes is the
default sound device.  

run   aplay -l

to see what alsa thinks are your sound devices and the order they were
found.

And you can run the script at 

You could also run the script below and post the link or run with
option --no-upload and post the output so people can see what your
system configuration is.

Note, this gives a *lot* of information, most of it only of use to
developers.
