Unfortunately some more testing revealed some issues with it,
specifically if pulse is running your complete config is replaced the bits in
the on_pulse_is_running directive. Which might not be what one actually wants :)
I couldn't find a proper solution for this. So i've changed the code to
optionally load config files. Just like the load hook does. Actually i just
optionally call the snd_config_hook_load function, but that's not actually in
the alsa API....
Also it now decides pulse is running as soon as the authorizing step begins
(just after the actually connection is setup), which should save some
round-trips and overhead.

The attached patch extends the alsa pulse plugin set with a alsa
configuration hook. Allowing one to specify some configuration parameters
that only come into effect when pulseaudio is running.
For example a configution file like:
@hooks [ {
func on_pulse_is_running
pcm.!default { type pulse }
ctl.!default { type pulse }
}
]
will redirect the default alsa pcm and ctl to pulse iff pulse is running.
(Assuming you defined the hook function correctly ofcourse)
This is usefull for distributions that don't want to force their users to
switch completely to pulseaudio, but have things a bit more dynamic :)
The solutions isn't optimal though. It will mean that every program loading
accessing alsa will try to make an (extra) connection to pulse to decide what
to do. But i think it's the best we can do for now (or at least that i can do
with my minimal knowledge of alsa).
A nicer solution would be a way to always specify the pulse plugin as default
and have a sort of fallback for when that fails.

Ignore hint sections defined by hand.
Those are heplful to get listed in various places, such as aplay -L

If stream connection failes, don't assume that stream is connected upon closing.

It adds support to report back XRUN to the application if one
happens. This is required to make some applications work on top of the
pulse plugin. One being XMMS, which checks if a song finished to play
by waiting for an XRUN (yes, I don't argue that XMMS shouldn't do
that, but nonetheless it is a good thing if XRUNs are reported
properly.)

It increases the "pre-buffering level" (i.e. start threshold) to the
full buffer size minus one period. This makes PA work a little bit
more like normal audio devices, and makes a few drop outs go away for
software which uses very small period sizes.
It also increases the initial maximum buffer size, which allows a
small overcommit. That's not really an issue, but cleaner nonetheless
so I smuggled it into this patch.

Added the minmax conditions for period_bytes and periods to pulse plugin.
This fixes ALSA bug#2601.

assert(!pcm->stream) shouldn't be checked when the PCM state is
SETUP, too (ALSA bug#3470).

This patch fixes the unexpected assert call at calling snd_pcm_hw_params
in PREPARED state. Since multiple hw_params calls are allowed, the pulse
plugin shouldn't call assert.
Handled in ALSA bug#3470.

Remove parameter constraints where we actually have none. Also, restrict
total buffer size to 4 MB as current versions of the PulseAudio server
will refuse streams larger than that.

Some stray mentions of the old Polypaudio name was still present in the
PulseAudio plug-in.

Polypaudio recently changed its name to PulseAudio which affects the
names of libraries of header files. Update the polyp, now pulse, plug-in
to follow this name change.
