We already do that, when we can match the audio device with the input device, in gnome-settings-daemon: https://git.gnome.org/browse/gnome-settings-daemon/tree/plugins/media-keys/gsd-media-keys-manager.c#n1184 It did work to make the volume buttons on a USB speaker control the USB speaker and nothing else. I have no idea how to change the LEDs though, but if they're exposed in sysfs, you'd probably change them in gnome-settings-daemon as well. I'd say "patches welcome" but in this case it will be "patches required". -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
