This is for users using windows XP, and realtek audio. Even if you're not using these specs, give it a try, it worked for me.
Go to the Control Panel> System> Go to the Hardware Tab and click "Device Manager".
Now, scroll down the list and find Sound, Video and Game Controllers. Then, right click and DISABLE "Unimode Half-Duplex Audio Device".
***If this works for you, bump the thread up so others can see it, as we've noticed there's little to no support thus far. I tried everything from Sound drivers, video updates, DX updates and this is what worked for me.
Onboard Realtek HD audio
