headphones soundcard

[Alexzzz]

Ok so i have the steelseries siberia v2 USB headphones and if you know what headphones im talking about so you probably know that the headphones comes with a sound card
its not a sound card that plugged to the mother board its plugged by USB ,
and when i plug it with the USB threw the sound card the headphones not working (at all)
and if i plug it with the normal analog entries the headphones works but not with the surround
the sound card makes a virtual 7.1 , so is there anything that i can do about it ?
in windows this sound card had drivers , but agian no drivers for linux ><
someone?

Any 3.5mm Jack will work on ubuntu, when your soundcard works. It will work.
