In current version of sound settings dialog (gnome-control-center 3.4.2-0ubuntu0.4) there is no way at all to set the sound card profile (see screenshot). Maybe it is a PEBKAC, but I really cannot guess how to set the 'Analogue stereo output' profile, so to completely disable the internal sound card input.
It is important to me as it seems to be the only way to have an USB microphone (like a webcam one) working as plugged in. Without this workaround, at the moment one has to set the USB mic as default source at each login (a no go for my parents... => audio chat screwed up). <rant>Of course, in gnome-shell everything works properly with the default sound settings menu. It is good to keep things simple, it is better keep them working.</rant> ** Attachment added: "audio-settings-dialog.png" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/985119/+attachment/3270553/+files/audio-settings-dialog.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/985119 Title: [soundnua]: doesn't offer 'Analogue stereo Output' option Status in “gnome-control-center” package in Ubuntu: Confirmed Status in “pulseaudio” package in Ubuntu: Confirmed Bug description: Ubuntu 12.04 beta2 updated to date In three different machines: Play 'Examples' audio files, or play bbc radio live streams, and click Record button in Sound Recorder.
