Lara talks at hyperspeed?

Solution 1:

From Tomb Raider Chronicles

Lara sounds like a chipmunk. Talks very fast.

Update the sound card driver. Confirmed problem on the Realtek Sound chip. If this still doesn't work go to your Windows Control Panel (->Start ->Settings ->Control Panel. Click Sound and Multimedia. Once you are in Sound and Multimedia Properties click the Audio tab. In the box 'Sound Playback' click Advanced, choose the Performance-tab and set the Hardware acceleration from Full acceleration to Basic acceleration or No Acceleration.

This sort of thing happens a lot with old games in general where the clock speed of component X didn't scale properly.
