PP client problem after upgrade to XP pro

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 intermitently sound OK but mostly sound like muffled clips. 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.

I installed updated drivers from my motherboard mfg. which seems to have fixed this problem. I have onboard sound so I guess the new audio driver solved the problem.
