7.1 Support on Ubuntu GNOME 14.4?

I know, I know. I should use better classic stereo headphones but this is what I got right now, and I don't think Trusty Tahr supports it. Is there an addon/plugins?

Why wouldn't it support it? Have you plugged in your speakers and checked?

Also matrix should tell you if your card is supported or not.

Oh. I should have been more clear. My mistake. I'm talking about a wireless headset.
