The more I dig in to this, the less I know. Back in 2009
or so, I upgraded the system in question to squeeze and I
remember discovering that /dev/dsp had gone away so I was
advised to install pulseaudio. I've slept a few nights since May
of 2009 so I do not remember everything that happened but I
imagine I did apt-get install pulseaudio. I did get /dev/dsp
back and have successfully used it ever since. I now have two
sound cards so there is /dev/dsp and /dev/dsp1 and they mostly
work except for the glitches. Alsa is also here and I think that
is what is really working.
There was no /etc/pulse/default.pa and no executable
file named pulseaudio anywhere on the system as well as no man
page for pulseaudio.
So, I decided to purge pulseaudio and start over as
there was a libpulseaudio on the system and
/etc/pulse/client.conf.
apt-get reported that pulseaudio was not installed so I
couldn't purge it so I did
apt-get install pulseaudio and got it. This brought more files
in to /etc/pulse including the default.pa file and the
executable for pulseaudio and it's man page.
pulseaudio can be started and runs and has no effect on
the glitches nor does it break anything. It's just another
running process.
It appears that pulseaudio can be an audio server and do
many things but I am not sure how it is supposed to fit in to
the scheme of things.
There is no native .pulse directory in my home directory
and, when I made one, nothing appeared there even after I
briefly ran pulseaudio.
This system goes back to the lenny distribution and it's
sound was, at one time, 100% derived from alsa. /dev/dsp always
blocks if you feed it more than one source so I am wondering if
there is some old legacy configuration file gumming up the
works. Sound basically works on this system with the exception
of the random glitches. If not for those, I would still think
that pulseaudio was running when it really wasn't here. Like
various famous people of our past have reportedly said, "It
ain't what you don't know that can hurt you but what you do know
that just ain't so."
