g0ukb: thank you for your suggestions. I had modified the USB-Audio.conf exactly as you suggested. ALSA is working with iec958 interface, which is routed to hw:1,1, but pulseaudio still redirects "S/PDIF output" to hw:1,0 (that is: Analog Stereo).
Probably your friend is running a different version of Ubuntu and/or Pulseaudio. I am running Ubuntu Ubuntu 14.04.4 LTS with the kernel 3.19.0-51-lowlatency (aka linux-image-lowlatency-lts-vivid) from trusty-updates repository. Have no idea what else can I do. :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1498129 Title: Asus Xonar U7 S/PDIF output not recognized by pulseaudio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1498129/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
