I appreciate and thank you for your comment!
What happened after 5th November? Well, I checked my computer box interior, everything was allright. And after I pulled back all my cables and stuff I lost my internet connection. I couldn't answer you back, and I was full of rage.
To be frankly, this is my work computer, and I work in 3rd shift. Two nights of work, and two days rest. If this is my home computer, I would reinstall my windows 7, simple as that. But under these circumstances I can't do that. So I ordered external audio card, hope to have luck with that.
I tried all those you write me in last msg. Nothing. I tried every possible combination with jacks and properties. Nothing.
