Thanks. Can you edit /usr/share/alsa/cards/USB-Audio.conf, scroll down to the "USB-Audio.pcm.iec958_device" section and add the following line:
"Sennheiser USB headset" 999 (including quotes) ...just above the similar "Logitech USB Headset" 999 line. Notice that your headset is spelled with a lowercase h. Save the file and reboot to test. If you can confirm this resolves your problem, I will be able to submit the attached patch, that makes this the default for Ubuntu and upstream ALSA in the future. ** Patch added: "0001-alsa-lib-conf-block-S-PDIF-access-for-Sennheiser-USB.patch" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/975941/+attachment/3058883/+files/0001-alsa-lib-conf-block-S-PDIF-access-for-Sennheiser-USB.patch ** Changed in: alsa-lib (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/975941 Title: [soundnua]: Spurious "Digital Output S/PDIF" output entry for USB headset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/975941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
