With system 6.07, you could just call SndStartFilePlay the way that it
is documented in Inside Macintosh VI. The sample source code given their
plays a 'snd ' resource from a file.

Since you said you are using 6.03, you could use bufferCmd and continueCmd,
but IM-VI says that a MacSE is not guaranteed to produce continuous sound
without the click, if you use these commands.

You could also take the less compatible route and find the old version
of technical note 19. This note explains how to play sounds without a
click.  This method can be applied to playing from disk, if you just
take a little time to think about it. Of course this method could break
any minute, although it hasn't, so far.

I recommend upgrading to 6.07 and trying to find a copy of IM-VI. I guess
the same information might be available in the MACE developer package that
at least used to be available from APDA. At least it should have some kind
of documentation for MACE, which should be another way to achieve what you
are trying to do.

>Does anyone know how to do it ?

Yes.
