Sound uses a type SAMPLE wich works very similar to the way BITMAP does.
Try this:

SAMPLE *my_sample;

my_sample = load_sample( SND1 );
play_sample(my_sample);

I think that's right.  Unfortunately there's no way to tell when the sound
is finished playing, so you might have to do another readkey() after this.
If you really don't want to have that readkey() at the end you could try
adding a delay equal to the length of the sample but that is really
sketchy so don't do it.
