HLDJ in Gmod? Help

[pRoD]

Ok i know there is another topic that is same like this, but i am having a different case.
I have Vista Home Prem.

-
Here we go:
HLDJ works on Counter Strike Source.
Does not work on TF2 or Gmod.
But i'm more worried about gmod...
I have a USB headset w/ mic plugged in. In console its all ok when i start and "la" is good. But when i select some song and press my hotkey, it just turns on the mic and you can hear what i say.

How to fix this?
Regards,

Find out where HLDJ is placing the "voice_input.wav" file. First delete all existing ones (do a search for it in the Steam directory), then load an audio file, and perform another search to find where HLDJ placed it. Depending on which version of Gmod this is (v6 or not) you may need to also set the Use Alternate Audio Path to the source sdk base folder.
