At the moment I am using my PS3 on my PC monitor with a HDMI to DVI adapter and a 2x RCA to 3.5mm adapter to my 3.5mm headset. The problem is I cannot talk on PSN with this setup and it's kind of annoying. A number of alternatives exist to solve this.
1) Get a USB headset. I can't get a normal PC one, as I wouldn't have any game sounds. Thus I need to pay like $60 for a Turtle Beach P11. Any cheap alternatives?
2) Some kind of adapter to change the mic plug to a USB connection? Ingame chat and sound come through the other plug anyway.
3) BUY A TV!!!!!!!!!!! But that requires money......
