Ive just bought Zero Hour and jave encountered a problem with the sound.
(also happened in Generals)
The game runs fine, no graphical glitches and the In Game sound is spot on, i get a problem with the FMV sequences between the levels, the sound goes on and off, the lip sync is completely wrong and the video keeps stalling.
This has never caused the game to crash however, just takes ages to load new levels.
XP 2600 (333) GF4600Ti 1024 DDR Creative Labs SB Audigy (first one) Abit KD7 Mobo Big HD's Loads of space left and defragged) CDRW & DVD (Same happens with both)
Ive tried running with or without a page file, lowering the graphics, changing the Hardware Acceleration in C P, altered the sample rate etc etc etc etc etc
Ive now run out of ideas, ANY BOFFINS/GENIUSES OUT THERE????
I had this problem, i scrapped my 4600 got a 5600 works fine now :D
