Gstreamer record audio from Virtual Machine Microphone or Sound output

[facepalm]

I am trying to record the sound from a Virtual Machine configured with
pulseaudio.  Below is the available devices in my settings:

I want to record the vm1-clone either the sound output or from the
microphone of vm1-clone. 

Tried pulsesrc but it is recording the desktop and not the VM.

Please help me to achieve this. I am thinking of getting the device address
of vm1-clone and apply it in pulsesrc device=<device> but I could not found
the device address of vm1-clone.

Thank you.
