So, I originally setup mine based on the PA wiki's "Perfect Setup".
It is rather
extensive and a lot of the stuff in there is from a time when there
was less support
for PA.

Here are the essentials:
Edit /etc/asound.conf (for all users) or ~/.asoundrc (per-user)
I have only these two entries in mine:

Neither of these files existed.  I didn't care about a per-user setting, so I just created an /etc/asound.conf and added the recommended lines below.

pcm.!default {
   type pulse
ctl.!default {
   type pulse

Make sure you are in the groups "audio", "pulse-access" and "pulse-rt"

I used vigr and vigr -s to edit the groups.  My user was already in "audio". I added it to "pulse-access" group.  And, I did not have a pulse-rt group.  I did not create the group.

Make sure that Pulse is being run automatically at startup (it should be,
I just remember when it was not, and I had to set it up myself).

It was already starting automatically with /etc/init.d/pulseaudio


The setting of the alsa default to pulse should make most things work,
but personally I set a number of things to PA explicitly. At least some of these
used to be required (they did not automatically use pulse and avoided the
alsa default or similar). Nowadays that may not be the case, I don't know.
Also they may have a PA driver that is different from the alsa driver, and
may work better than redirected alsa.

in ~/.mplayer/config: ao = pulse

in ~/.xine/config: audio.driver:pulseaudio

in ~/.vlcrc or ~/.config/vlc/vlcrc: aout=pulse

in /etc/libao.conf: default_driver=pulse

I did not have the mplayer or xine config files above files.  So, I created them and add the recommended lines.  I had the ~/.config/vlc/vlcrc.  The aout directive was present, but was commented out and had no value.  So, I set it.  I changed the /etc/libao.conf from default_driver=alsa to default_driver=pulse.

for gstreamer:
gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosink pulsesink
gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosrc pulsesrc
gconftool-2 -t string --set
/system/gstreamer/0.10/default/musicaudiosink pulsesink
gconftool-2 -t string --set
/system/gstreamer/0.10/default/chataudiosink pulsesink

I ran the gconftool-2 commands.

KDE's Phonon uses vlc, mplayer or gstreamer, so the above should cover
that as well

SDL (used for some games) can be set to explicitly use PA with:
export SDL_AUDIODRIVER=pulse
(needs to be done in a startup script like ~/.bashrc to be permanent)

I added the export to the .bashrc.  I also executed it at the command line so I didn't have to log out and back in.

I restarted pulseaudio with: /etc/init.d/pulseaudio restart

This did not seem to work.  So, I rebooted.  This seems to work.  I was able to play a movie with sound on VLC, Minecraft and Skype all at once without breaking anything.

As far as I remember that is about it. As I said, setting those explicitly
may not be needed anymore, I just don't know.

Thank you so much for sticking with me.  I appreciate everyone's comments.  I hope that someone with find this thread useful in the future. 

Just to clarify with Kelly about what "complicated" stands for :-)

IMHO you are going to get what you want in two steps:
killall pulseaudio && aptitude install jackd qjackctl


L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.
