Raymond: >Why are three playback devices?
1) is analog output 2) is digital S/PDIF stereo output 3) some other digital output Playing to the third device lights the "digital output" indicator, but I do not get any sound. Looks like some sort of S/PDIF output, not supported by my external DAC. Reading documentation I'd guess it is "Dolby Digital or DTS output", because the manual reads "For Dolby Digital or DTS output, check that the AV receiver is in the correct decoding mode." Also, searching on the Internet suggests that it is DDL: Dolby Digital Live, which can be selected for the S/PDIF output when using Windows software. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1498129 Title: Asus Xonar U7 S/PDIF output not recognized by pulseaudio Status in alsa-driver package in Ubuntu: New Bug description: 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.
