"I try with the PowerPoint Viewer + Wine (pptview) and the sound works but sometimes this application freezes the s.o.
Any solution?"
Yes. What I did was install Virtualbox using Windows XP as a VM. Then it's a simple matter to install either Powerpoint Viewer or Powerpoint. This works perfectly, but it seems rather silly to me to install all this machinery just to be able to get sound with powerpoint presentations!
