I have a clean install of Wheezy running under Xfce on a basic desktop computer. I am looking to get audio working in a straightforward way, i dont want to be doing anything fancy. The "basic" docs ive looked at are often very complicated and talk aboutt hings i dont want to do.

Right now i have plugged-in speakers and a USB audio device, and will soon have another USB device. In Ubuntu I would go to the Gnome audio thing that was available from all the menus, and select the output device, and that's what would work for all apps. In Debian the Alsa Mixer that launches from the Xfce widget doesnt seem to control where the sound goes, so i have to start messing around in each app to choose the output. This is a pain; i want to switch from the plugged-in speakers to the USB device in one place and for everything, whether its XMMS or Flash videos in Firefox or VLC or whatever.

Sound has always worked for all of my Debian installs.  I tend to have
Gnome installed, though, even if I don't always use it.  The controls
you are looking for are possibly part of a gnome package.  I don't have
it on my system right now...  Try typing in a terminal:

gnome-

and hit the tab key twice.  You should get a list of commands for
various gnome utilities.  Maybe one of them will stand out.

There are also some pulseaudio utilities you may want to install and see
if they are what you're looking for.  Use synaptic and search for:

padevchooser
paman
paprefs
pavucontrol

But in both cases i assume the answer will depend on my overall solution so I am only mention this in passing.

xev will help you find key codes for all the keys on your keyboard.  Use
that in conjunction with xmodmap to map your keys to certain functions.
Volume can be adjusted using the amixer command.  Something like this:

amixer sset Master,0 10+
amixer sset Master,0 10-
