Okay, update with all the solutions everyone has chipped in. (THANKS AGAIN)
both Christof's and Jack's solution still create audio drops. Now I am
testing Jean-Yves's patch and seems to do the trick.
again, thank you all. If anyone has another idea, I will be interested in
looking at other solutions (just for the heck of it).
ps. Thanks Jack, I will try changing the [block]
cheers
