Stereo Mix - getting reverberation, no driver SFX enabled.

Programs tested: Hypercam, Bandicam (using WASAPI)
Windows 7
Headphone w/ Mic

I get this reverb when playing back videos I've taken on my desktop, ie Youtube or otherwise. When playing them on the site's they're fine, but the recording is louder(levels, I assume) and has reverb. It's not quite an echo, but it's like it's playing in a hallway or amphitheater.

I've tried disabling the microphone, changing kHz, reviewing the RealTek control panel to see if there are any unusual sound effects/"corrections" (none).

Using the PCM codec seems to do it *slightly* less than MPEG-1 L2. Mono/Stereo makes no difference. I'm hesitant about changing codecs but I'm already using Realtek so I dunno what to do. :/

This would seem to be the program you are using to recording the videos and not an actual "sound card" problem.
