Fraps Video Recording

[Zoltar]

I managed to get my hands on Fraps the other day.
Nice program.

So i was recording some CSS pwnage.
I start up the video and there is no sound. Thats gay.
I did all i could, read every FAQ and still nothing.

Turns out, it record all sounds, just not sounds from games on the Source Engine. Lovely.

Any ideas how to fix this?

Thanks
