how to record voice from headset and microphone simultenousl

I am using windows 7 and audacity application 2.1.1
Can you please advise how can i record the sound in headset and my voice via microphone simultaneously. It seems my sound card does not support stero mix.
Please adivse how this can be achieved. I have tried the the recording listen tab and by clicking listen to this device but there is lot of eco and does not fit my requirement.
Any suggestion/help would be greatly appreciated.

If you’re on Windows, you might try VoiceMeeter.


Bear in mind you won’t be able to edit your voice and the song separately unless VoiceMeeter has a way of putting them in separate tracks.

A better method is to import the music into Audacity then record from the mic input.
