Sorry if i was unclear, i'll try to clarify (also some new information)
First of all, everything worked until thursday/friday. I know it for a fact, as i've used my pc normally for a month.
On thursday evening everything worked. Then at the end i accidentally pulled headset cord with my leg, and the headset fell. I did not immediately check if it worked, just picked it up and left it at that.
24 hours later, at friday evening i found out, that my mic does not work. It does not pickup what i speak, instead it picks up what i hear in headphones (music, system sounds, etc).
First i've checked mic parameters both in realtek manager and in standard windows control panel. I found nothing wrong. Then i've rebooted to linux and found out the same problem. Tries several other linux live usb's - same problem. So, it is not the OS, and not the configuration.
Then i checked back panel. Here headphones still work fine, and mic records static noise.
Then i tried physically disconnecting front panel HD audio cable from the motherboard. Still static on back panel mic.
I've recorded what exactly mic picks up from front panel, and it seems like some cross-talk between input and output channels (it's not exactly the sound i hear in headphones, just one channel present and it is somewhat silent).
Odd thing is that OS still sees both mic ports and detects connect/disconnect events for them just fine. Headphones also work fine.
Now for the scary part.
Knowing full well thart RMA'ing stuff will take up to a month, leaving me without PC, yesterday i went and bought a different motherboard (with intent to send the old one for diagnostics/repair).
I've installed this new board, connected my head set to the front panel and...got the same thing. Went to the back panel - same.
I went to my friend and took his usb sound card for testing. I put my headset into it and got the same effect.
Still unsure if it is just headset dead or i just fried the second mother board, this morning i went and got myself new cheap headset for testing.
I put it to back panel first. It seems to work - no cross talk, voice is recorded.
I put it to front panel then - it cross talks. Then after a minute mic fills with heavy noise. I put it back at the back panel - only noise now.
So, it looks like my pc case front panel kills headsets. And probably motherboards - im still not sure.
