PP client problem after XP pro install

I performed a clean install of XP pro on my machine; cleared and reformated the disk so not just an upgrade from Win 2k. The PP client sounds are not working properly in both ring and tourny tables. The dealing and chip sounds are mostly muffled and clipped but intermitently they will sound normal. It sounds kind of like a bad streaming audio with the sounds out of synch w/ the actions. Otherwise, tables seem to function OK. I have uninstalled the program several times and installed new downloads from the site, v1.2 build #87 10/07/05. I have checked the .wav files in the program and they seem OK and all other audio functions in XP seem OK. I would appreciate any ideas that anyone has about this problem.
