My new headset not recording System Audio Help.

[eabos0726]

I use Audacity and I would use WASAPI and did not need Stereo Mix enabled with my old headset. Now with my new headset I have to use Stereo Mix, WASAPI won't work anymore, pretty weird issue to say the least. I installed Asus RealtekDriver 6.0.1.7354 I record in Mono. My mic boost is at +0.0db. I plugged in green jack in headphone port to record system audio and it does not work. I had no issue with my old headset recording system audio. Now I have an issue with this new headset. Any help woukd be appreciated. Here is the new headset I bought from Amazon. If you want to buy this headset for yourselves I highly recommend them, they sound great and mic picks up sound really well.
