[AD] Allegro fails to initialize sound under Pulseaudio

[Steven Brown <steven.w.j.brown@xxxxxxxxxx>]

Hey all,

FYI: Pulseaudio, formerly Polypaudio, is a sound server meant as an 
replacement for ESD.  It's gaining a lot of ground in the linux desktop 
space.

Anyways, I was testing a game that uses Allegro the other day, and 
discovered that it fails to initialize sound.  Allegro detects and tries 
to initialize using ALSA, which is fine, as Pulseaudio has an ALSA 
plugin.  But it fails, which is less fine.  :P 

I've filed a bug with the Pulseaudio people here:

   http://www.pulseaudio.org/ticket/133

(It includes a simple sound initialization application and output from 
my computer.)

After talking with someone from #pulseaudio, he said that it may have 
something to do with Allegro requesting ALSA in MMAP mode, which the 
ALSA plugin for Pulseaudio does not support.  Also, forcing Allegro to 
initialize with ESD works with Pulseaudio, but it is *much* too laggy 
and certainly unusable in any game.

I just thought I should let you know, if anyone here has an idea to the 
problem.  :)

Cheers.
