Okay, so I'm trying to record a video with my Hypercam 2 (on Windows 7 Home Premium 64-bit if that matters). I both enable Stereo Mix as my default recording device and enable it through Hypercam 2. I record, play back, no sound. I then choose the default recording device through Hypercam 2, and still no sound. When I go into Speakers > Recording Devices, it doesn't pick up anything unless I turn the volume up loud. On the video I recorded before that, it picked up the audio (almost) fine, with the settings exactly the same. I just can't seem to figure it out.
