The in-game audio is not working at all, no music in the menus, no effects or nothing while playing (Microsoft Live sound does work, though).
This is the environment:
- Steam client
- Windows 8 64 bits
- ASUS P7P55D integrated sound card for audio
The sound card is connected to a receiver through SPDIF. Everything else works without a problem, both in 5.1 (movies) and stereo (music and games). I do not use AC3 or any encoder for 5.1 gaming. All of the other games I have do not have any sound issue. I have also tried to connect headphones to the corresponding jack in the sound card with the same bad result.
