Actually, I do.  And it doesn't.  Thats something I'm rather sure of.

Which is shorter that the calculated one.  Are you denying that ?   If so,
on what grounds ?

Also, either in this thread or the previous one about the same subject I've
mentioned that I can actually make the sound come out as long as the
calculation shows it should.   So yes, I'm "pretty sure" (understatement)
that what that linked-to code emits in regard to sound is shorter than what
it should be.

:-)   How many of those people have actually tried to run the code ?   Apart
from Jim, NONE.  And alas, he did that on a PC, not an RPi.   Different OS,
different hardware.  Not comparable.

:-)  I've done a number of different tests (with measuring time being one of
them) all showing that the sound indeed gets cut off.

Why do you think I think that ?  Is that the /only/ possibility that would
make my "too short" claim valid ?    Are you sure ?

And no, a few different tests I did (one of which I posted) have already
shown that the /other/ possibility doesn't exist.    Yes, I have also
thought of that.

What makes you think that "the correct ammount of data" is actually being
played ?    What do you base that on ?   Whisfull thinking perhaps ?   :-(

Also, although I've not mentioned it, I did a test (on two different
examples) where I kept all buffers Zero, but for (the last part of) the last
one (upto half a seconds worth of it).  Guess what I didn't hear.


I *really* wish you would be able to run that example code for yourself and
duplicate my tests and see for yourself.  Now you are just contradicting me
for the heck of it.    Sigh ...
