-.- your settings....

 

go into settings, sound, and change like the one that is down to 0 to where ever u want.

 

*NOTE: If this only happends in zam you need to load the mod first then change the sound settings!

Your sound device might be changed. In game menu, try every selections till you get your sound on.

I was already doing this, but it doesnt worked. So i reinstalled my game and tryed again and it worked. Thank you for reply.

or you could just have pressed reset defualt settings but ok ok that works to. ^^

I had the same problem when I just got BO1 just go to sound Icon in windows 7 or 8 if you have it xD and right button click and click on SOUNDS then, there you can change some settings and maybe thats can help you it did help me.
