"There is no need for anyone to have a computer in their home."

I program the Mac in assembly language, and appear to be the only person
in all of Bloomington to do so.  Thus, I have no recourse but to seek
experienced programmers elsewhere.

I've heard that the Inside Mac Volume V description of the Sound Manager
is badly written and self-contradictory.  After immersing myself in it
these past few days, I have no trouble believing this.  ALL I WANT TO DO
is play a particular type 2 'snd ' resource, which is a digitally-sampled
sound.  No fancy pitch changes.  No frills.  Just play the damn thing as
recorded!

The 'snd ' is loaded into memory.  It's not going anywhere.  I'm willing
to allocate my own section of memory for the SndChannel record.  I know
where that is too.  My program has already been loaded into a nice cozy
spot in the system heap, and I've redirected a trap to call my routine
first, which calls the original trap and then returns to play the sound.
I.e., whenever this particular trap gets called, my 'snd ' is to be played.

The above routine is working just fine as it is.  Right now, it merely
does a _SysBeep whenever this trap is activated.  But how in hell do
you get the Sound Manager to play the sound?  Any guidance on this
question would be dearly appreciated.


As a side question:  I want this sound to be played whenever the user
hits a key, but ONLY when TextEdit is active.  When the user is in the
Finder or anywhere else where keystrokes do not produce characters on
the screen, I do NOT want my sound to be played.  The way I'm doing this
now is by redirecting the trap _TEKey.  I haven't tested it in many
different applications yet, but this seems to work as I want it too.

Can anyone else think of a different, perhaps better, way?  (Just for
more options to consider.)

Be seeing you...
