Only the microphone is not to be used.
The integrated sound card, the headset and PC, you can adjust various settings individually.
What is also very good effect on the sound.
The only problem is that the microphone is incredibly quiet by connecting via sound card (USB). You can not set the microphone gain, but only the normal volume in the software of Creative.
For this reason I have always connected the microphone directly to the jack connection. But even there you have trouble hearing in Skype, Mumble, TS, etc. me, despite +30 dB (maximum) microphone gain in Windows.
I'm not sure if I only have the problem, but if you google after that, there are many people who have exactly the same problem.
