Dear Bug Team!
There's a race condition in alsaplay.c which prevents sound-files (or
loaded sounds) from playing.
To reproduce the bug, start xemacs and evaluate
(play-sound-file "/usr/share/xemacs/xemacs-packages/etc/sounds/whistle.au" 100)
(adjust path to suit). Nothing happens.
No idea how system-dependent or recent this is.
I tracked the problem down to the fact that the existing code calls
snd_pcm_close on the device handle immediately after writing to it.
I guess this worked once, maybe what 'blocking' means has changed, but
in an case this patch will fix it (discovered by comparing the
equivalent code in emacs, which doesn't have this problem):

if ((err = snd_pcm_writei (pcm_handle, data, length)) < 0)
goto error_mixer;
+ /* wait for it to finish -- added by HST to fix killing the thing
+ before it's actually played much if anything */
+ if ((err = snd_pcm_drain (pcm_handle)) < 0)
+ goto error_mixer;

/* Put the volume back the way it used to be */
reset_volume (&mix);
