help pl0x, audio problem

[simplebob]

So I recently got a Wii u along with the PS3, and i do not own a TV(i know) and i play them on my computer monitor that does not have audio but instead i use my steel series wireless h on both of them.

 

problem here is I would still like to listen to music/talk to friends on Skype or steam on my PC while still be able to play on my consoles as switching display modes also changes what I can hear through my headphones.

 

So I was wondering if there's any expansion card out there that can serve audio inputs to directly feed them to my computer.

 

sorry for the nooby question and i hope this is in the right category

Its pretty simple really get a rca to 3.5mm jack like dis http://www.ebay.co.uk/itm/3-5MM-STEREO-JACK-MALE-TO-2X-RCA-PHONO-FEMALE-ADAPTER-/360300626060 then get the composite cables from your ps3 and plug them in as well as the hdmi this will output sound to the red and white cables plug these two in to the red and white female ports on the adapter the plug the 3.5mm in to the back of your pc through the light blue line in connector. 

 

PM me if you need any specific help with the setup ive got the same thing on my pc with my xbox 360
