Did all this still have no sound through speakers when playing only this Game NW2 ??? This sucks big

Hi and thanks for reaching out. I hope you’re doing well. I'm an Independent Advisor and a Microsoft user like you and I'll be happy to help you.

There could be several reasons why Modern Warfare 2 is not making any sound on your Xbox. Here are some possible solutions you can try:

1. Check the volume settings on your Xbox and make sure that the volume for Modern Warfare 2 is not set to zero.

2. Check the audio settings on your television or display device to ensure that the volume is not turned down or muted.

3. Make sure that the audio cables between your Xbox and your television or display device are securely connected and functioning properly.

4. Restart your Xbox and try launching Modern Warfare 2 again.

5. Check for updates to Modern Warfare 2 and install any available updates.

6. Uninstall and then reinstall Modern Warfare 2.

7. If none of these solutions work, try playing the game with a different pair of headphones or speakers to see if the issue is with the audio output device.

If you have tried all of these solutions and the problem persists, it is possible that there may be a problem with the game itself so what I can recommend is to contact Activision Support through this link; https://support.activision.com/options for further assistance.

No Surround sound ? Is that true ?.

Yes, the Optical and HDMI In port can't produce surround sound.
