I cannot record audio from HyCam 2

[ElTremendoGalxo]

NOTE: I have the High Definition Audio Driver Updated to the last version. It is named like that so I can't search a more recent version.

Hi everyone, the name's Galx, and I will present you the most common issue in society: Can't record Internal PC Audio.
Channel Mixes (Stereo Mix, System Mix, etc if available) are not able to be used, and all the drivers are up-to-date. Can you describe me the issue?
I'm trying to do a SRB2 Analog Horror and I need a LQ recorder, something like HyCam2 Unregistered, I have Audio Record on.
Also, I do not have any kind of microphone.
Can someone help?
