I start Vspectrum them play the video and while the video is playing you will see the frequency traces on the screen as the video plays. You may need to go into your windows volume control and make sure the recoding portion is not muted out.

It doesn't seem like it wants to work.

Are you playing to through the speakers into a mic ?

I have gotten close , but I still get the yellow lines.

The audio is playing through the speakers but as I said you have to go into your volume control and see what your settings are for recordings.
