Pour ceux et celles qui n'auraient pas les voix des protagonistes, il faut revenir à une version précédente du fichier EAX.dll, en version 4 dans le jeu.

Tout est expliqué à la page suivante:

"If you are having audio problems in Assassin's Creed, particularly with audio glitches or missing sound, this is probably due to the game's use of EAX/DirectSound. The use of EAX can cause problems, particularly on sound cards which provide minimal EAX support, such as onboard audio. You can try one or all of the following to see if it helps (try them in the order shown):

1. Make absolutely certain you have the latest audio drivers for your sound device, and they are cleanly installed - see the Driver Installation chapter of the TweakGuides Tweaking Companion for links and details.

2. Make sure to disable any additional EAX or CMSS effects in your sound card's control panel.

3. If running Windows XP go to the Windows Control Panel> Sounds and Audio Devices> Audio> Advanced> Performance tab and move the 'Hardware Acceleration' slider to the first notch from the far left (i.e. Basic Acceleration).

4. Edit your DARE.ini file to reduce or increase the value of the NB_AUDIBLE_VOICES variable; also try setting DISABLE_OPTIMISATION to =TRUE - see the Advanced Tweaking section for more details of these.

5. Go to your \Program Files\Ubisoft\Assassin's Creed directory and backup the eax.dll file there, then replace it with this one: eax.dll.

In the end however, if the steps above don't work, then it's likely you will either have to wait for newer audio drivers from your sound device manufacturer, or a patch from Ubisoft to fix this aspect of the game."

Ça fonctionne sans soucis chez moi ;)

Reste encore un sale bug avec le postFX activé sur une X11950XT, qui rend la vision d'aigle ingérable (là encore, suffit de désactiver cette option).
