Hi i have just installed Crysis and crysis runs perfect. I have just brought a new graphics card to run (not just for that game have course hehe). But i have also installed sandbox2 but when running sand box there is a humming sound coming from the speakes and i have tried it with head phones and still the sound is there. I can turn the volume down and it goes but i was just wondering if there is a way to stop with the sound on.
Have you tried restarting the sandbox. If it keeps occurring try running the normal Crysis and configuring with the sound settings. After that, play atleast one level and then return back to the sandbox.
Oh, I forgot to mention, this also happened to me. A simple configure with the sound settings sorted this out. Make sure your sound quality is set to high, and that your sound card is compatible.
If it still occurs it could be your speakers. If you take them out for a while, blow into them and check for any damage. You can also configure your speakers from the desktop located in the bottom right corner with a icon of a speaker.
There's more alternative ways such as changing sound devices if the problem still exists. But hey, I don't know much it could be none of these and just a simple error which can be fixed in a few clicks.
