For those who really want to get rid of the dialog in the meantime, here is what I did in order to quick-fix my own system. I made a simple hack, and followed the steps listed here to rebuild the unity-settings-daemon package
https://help.ubuntu.com/community/UpdatingADeb The hack (to be done in place of the "patch -p1" step in the guide) is to disable the new functionality; I did this in a possibly very inappropriate way, please don't blame me too much. I edited the file unity-settings-daemon-14.04.0+14.04.20140414/plugins/media-keys/what- did-you-plug-in/dialog-window.c and added "return 0;" as the very first line of the function wdypi_dialog_run. There may be better ways. My two cents on the solution is to chose a fallback, issue a notification, and allow the user to configure the default behaviour in the audio settings. That would be less in the way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1297790 Title: "Unknown audio device" dialog pops up every time I plug in headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-settings-daemon/+bug/1297790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
