You may have to use "alsamixer" first. When you open it, use the F6 key
to change to your "other" sound sources/outputs by usually having to
un-mute them. If alsa doesn't see your device, pulse won't either. Pulse
sits on top of alsa and merely directs things audio to where you want
them to be. But, if something is muted in alsa, pulse cannot deal with
it, as far as I know.
