My OS is Win Vista Home Premium, I'm using the trial version of Debut, and I want to record what I hear from my speakers. I think my configuration is wrong; I previosly had been using my headphones for playback & recording, but the recording didn't work for me with Debut, hence I want to record with my headset, but not via the microphone? I had to change my settings because of that. My sound settings are:

At Debut > Option > Device tab > Audio section, for Sound Devices the choices are:

[Default Sound In]

Line in [High Definition Audio Device]

Aux [High Definition Audio Device]

Microphone [High Definition Audio Device]

Audio input has these choices:

Windows Record Mixer

Master Volume

What is Record Volume?

My PCs sound configuration is set to use my headset for playback & recording. I want to use the headset for recording instead of having to switch to my speakers for playback since I don't have them plugged in.
