How could I play the DivX/AC3 movie with sound?

[naswer]

I have a DivX/AC3 movie ,but I can't play it back with sound! Why?
The movie information:

Video stream:
Low motion DivX MPEG-4, 640x352, 24 bit, 79833 frm, 25.0000 frm/s, 1459.721 kbit/s

Audio stream:
DVM, 48000 Hz, 384.000 kbit/s, 5 channels

I have used DivX Player 2.0 Alpha, WinDVD4, PowerDVD4, BSplayer & Micro DVD player to play it back, but still without sound!

I install a filter names ac3-filter, then I could play the movie with sound!
