Actually, I've found with a couple of USB audio devices that digital
output modes (all that are not simple analog) are often missing. Does
that sound like the same issue?

Title:
USB Soundcard is not detected everytime, especially on resume from
suspend
Status in pulseaudio package in Ubuntu:
New
Bug description:
Creative X-Fi USB seems not to be detected correctly. First time
there's no possiblity to change output type to 5.1 (no menu in control
center). After detaching and hooking up again it was not there. The
third time I was able to detect it.
It might be something to do with kernel.
I have such information in dmesg:
