Thank you, Raymond. I will try this patch and see whether the error message "cannot get ctl value" goes away.
However, as much as I can tell, my problem is not related to this error message. ALsamixer works just fine (with "ignore_ctl_error=1", see above), but pulseaudio does not recognize the S/PDIF sink of the card. -- 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
