Public bug reported: The external USB audio card Asus Xonar U7 is capable of both analog and digital output. ALSA name for the digital (S/PDIF) output is hw:1,1, and it is listed in aplay -l output, and aplay can output to it: aplay -D plughw:1,1 sample.wav. So, direct alsa sound works fine.
However, pulseadio does not recognize the digital output of Xonar U7, it offers only analog output.
