EndlessKnight: At the title screen and during gameplay the sound works fine, but during the cinematics, I get no sound. Fortunately, there are subtitles, but it would be nice to fix this issue.

Win 7 64-bit with the sound coming from my nVidia GeForce 560. It is linked to my HDTV (via HDMI). I may try inserting my old Sound Blaster Audigy 2, and seeing if that fixes anything. The cinematics have proper sound on my Win XP (32-bit) netbook, but the game runs a spec slow on that.

The executable file was pre-set by GOG.com to run as admin, in Win XP (Pack 3) compatibility mode, with visual themes, desktop composition and display scaling disabled.

The video files appear to be .wmv files. This causes me to wonder if it's due to the older version of Windows Media Player on the XP system vs the new one on the Win 7 (64-bit) computer.

Any ideas?
