This is how play-sound is implemented.  It is run after all messages
that it knows about at the time are filtered already (or, it is supposed
to be).

I think you want another solution, run your play-sound command
asynchronously if it isn't already running, and when you start it, just
save something to say it is.

i.e. in a script, do something like:

#!/bin/sh

stamp=$HOME/.newmailsound

if [ ! -f $stamp ] ; 
   ( touch $stamp ; play-sound ; rm $stamp ) &
fi


Yes it has a small race, and wont clean up if something goes down, but
it should suffice.

(this assumes play-sound blocks until it is complete, you could add
arbitrary sleeps).
