load_sample returns a pointer to a SAMPLE.  Declare a SAMPLE* called,
say... sound.

SAMPLE* sound;

Rewrite this part to say:

sound = load_sample(SND1);

>  play_sample(SND1 *, 255, 128, 1000, 0);

No.  SND1 is actually "test.wav".  You want to play the sample that you
loaded.  You want...

play_sample(sound, 255, 128, 1000, 0);

>  stop_sample(SND1 *);

Now, if you stop playing the sound immediately after starting, you'll be
lucky if you hear so much as a pop.  I haven't used Allegro sound much,
but I remember that if I wanted to know when a sound stopped I had to
use the voice functions.

Also, destroy_sample(sound); should go here.

Maybe you should move this to the Allegro list.  Go to
http://www.talula.demon.co.uk/allegro/maillist.html and read carefully
on how to subscribe (write your subscription request to
listserv AT canvaslink DOT com).

Quote:

To subscribe to one of the lists, write to listserv AT canvaslink DOT com with
the text "subscribe {list} myname" in the body of your message, where
{list} is one of allegro, agp, or conductors.

We've had a lot of trouble with people trying to sign up by writing to
the main list addresses.  Please don't do that.
