No Sound on DVD playback

I have a creative xfi xtreme gamer, which works fine, I get all sound and features I should in Win 7...that is that I use or am aware of

I seriously just put another hard drive in my system and closed the case. Fired it up and BAM, no sound when playing DVD's.

I have looked everywhere and double checked all settings, but again nothing should have changed. Any suggestions on what i might have done.

DVD drive is SATA and there is no audio cable to unplug, this worked yesterday - how the heck did i mess this up

Thank you for replying.

Everything works normally, except DVD audio.

Sound is present in Windows, CD playback, games, etc. When trying to play a DVD I get picture and no sound.

I have removed the other SATA hard drive to no avail. The only reason I mentioned it was just to indicate I was rooting around in the system, but thinking about it now i realize there are no audio plugs or cords etc that I might have left undone.

I only have 1 DVD drive in the system which is playing CD's properly and video from DVD's but no sound.

All of this worked literally hours ago.

Hmmm,

Wierd, problem solved.

I tried re-installing the drivers and running update, it didn't resolve the issue.

On a whim, I did it again, and it worked.

Thanks for your time and help.
