Not completely sure, but the way I understand pulseaudio works is that it does *not* publish available Alsa devices to the application. If all the sound passes through the server, there is not much point for the app to know which device is going to be used for playing and recording. The app only sees pulseaudio input and output, and uses that. So which app uses which alsa devices is configured within pulseaudio (using pavucontrol), rather than in the app itself. This is not the question of available functionality, but rather where the controls reside. It is similar to the functionality of an X server --- once a new app is started and it tries to draw its own window on the screen, it is not up to this app to decide where exactly will the window be drawn, but rather it is up to the window manager. It's window may be moved around, minimized, maximized, covered by another one, on this or that desktop, etc., and all this is done transparently, without the app knowing much about it. The same thing is with audio server (of course, it's much simpler due to its nature) --- app talks to pulseaudio and says "I want to play something and record something", and the pulseaudio is the one to decide what will be the actual source and sink used for each particular app. So just like when you want to move the window around you give instructions to the window manager and *not* the app itself, so also when you choose this or that audio source/sink you give instructions to pulseaudio and *not* the app itself. Finally, keep in mind that a proper audio server is there to enhance functionality, not to reduce it. :-) HTH, :-) Marko

GNOME should allow you to choose which device for speaker input. Doesn't the webcam mike show up under Sound Properties (right click on speaker in bar)?
