I'm trying to test this on FC4 test 3 with alsa driver 1.0.9rc3. grep isn't
turning up the original lines reported as causing the problem so maybe
they've been removed. Can someone point me to the file where this
problematic code was originally located?

There's still a clipping problem using alsa with gnome speech. I'd like to
see if it's being caused by this same bug.

parente: The code that i posted is an example of WORKAROUND for the bug.
not the code from alsa, but something an application writer can do to get
around of the bug in ALSA. I have not investigated where in ALSA the bug
actually lies.
