No Sound while playing DVDs

[abhijeet_ghosh]

I have a P4 2.60c, 256 MB DDR RAM and Windows XP SP2. The problem is that I don't get any sound (only video) while playing dvds on my PC. I have a Samsung SD-616Q DVD ROM Drive. I have tried PowerDVD & RealOne player to no avail. Windows Media Player doesn't even play the DVDs. But these DVDs play fine on my DVD player (for the TV). Please help.

I have on board sound (SoundMAX on an Intel D865GBF motherboard)). Well I have kind of solved my problem. I installed Fraunhofer DVD codecs after which I am able to play DVDs properly in Windows Media Player. But now I am unable to play DVDs in PowerDVD. PowerDVD gives an error saying "Unable to build DVD graph".
