I was messing with my Saucy install and I've lost all USB sound devices from ALSA/Pulseaudio/Gstreamer...
They are fully recognized if I boot from LiveCd (Saucy and update/upgrade to same state as install on HD...) so HW is working OK...
None of several USB sound DAC's is being seen/recognized...
Sound works OK through Radeon and through built-in-audio (S/PDIF)...
I might have erased something that in fact is needed (cleaned via gtkorphan as I do on many occasions), but I doubt that that is what have happened...

As You can see USB PCM2706 (for example) is recognized by system. It is only not recognized by ALSA and hence by PulseAudio...

Any ideas?
Update₁: I founf solution... Somehow in file /etc/modprobe.d/alsa-base.conf line
Code:
sna_usb_audio: index=-2
resutfaced again. Commenting it out solved the problem...
Also, just in case
Code:
modprobe -a snd-usb-audio
was performed... Now it remains to be seen if it survives reboot...
As they say: morning is smarter than midnight...
Update₂: It works...
Long live my notebook (paper, old-school) logs...
