Pavucontrol is not installed by default. Check and see if it's installed
first. Then launch it from command line as you were asked to do. It's
fairly easy to use. You select the layout of your sound system under
Configuration. It should be showing all of your sound devices.
A paid of stereo speakers? Or 5.1 or 7.1? You have to tell pulse what
you have installed externally. Same for a USB headset. If you don't have
S/PDIF hardware connected to your sound chip, then you sure wouldn't
select that as your hardware configuration. Because it's capable,
doesn't mean it's used in the real world in your setup. This is easy.
Leave pavucontrol running and launch something that has audio while you
are in the playback tab. Once your app launches, you should see the
sound bar fluttering. If it's showing your 5.1 setup and you wish to use
your USB headset, you can switch on the fly. THAT is when pulse makes
sense. Your speakers are your "output devices" and input devices are
things like microphones.
I have a 5.1 speaker system and I do not use a mike with my sound card.
So, under configuration, I have 5.1 selected with no input. I use my USB
headset and that is configured "stereo" and "mono" input for the boom
mike. Once you wrap your brains around it, there is nothing simpler to
use! Then, you'll love it. But swapping between devices, on the fly, is
the best part. Plus, if you use your headset for Firefox, the next time
you use firefox, it'll switch to headset, even if you just used your box
speakers to watch a DVD. :) Ric
