OpenAL Problems with Pulseaudio

I hope I'm asking this in the right place. I am having issues with
OpenAL 1.11.753 working with Pulseaudio. I am running Ubuntu 9.10
"Karmic Koala" (2.6.31-19-generic kernel) with Pulseaudio 0.9.19 on ALSA
1.0.20-3. I did my testing using gmplayer with audio preferences set for
"OpenAL".

OpenAL works "okay" using the ALSA driver and ALSA emulation under
Pulseaudio (though it requires a rather high period size set in
~/.alsoftrc to keep OpenAL from opening and closing a million sinks per
second in Pulseaudio). However, when I change the driver to "Pulse" and
attempt to play something in gmplayer, gmplayer hangs. This is the same
for any other application that uses OpenAL (for example, Second Life). I
have observed, using Pulseaudio Manager (paman), that the application
will create a new sink in Pulseaudio named "Playback Stream", which is
normal; but that's as far as the application gets, as it hangs
completely. If I kill the sink, the application becomes responsive
again. This same application works fine if I change OpenAL's driver to
"ALSA" from within ~/.alsoftrc.

I attempted to compile OpenAL 1.11.753 from source, but it did not
compile with ALSA support. Again, it would not work correctly with
Pulseaudio.

Is there something I might be missing or not doing correctly?

TIA,
Brian
