I have Siberia V2's, had them for about 3 weeks now. I didnt use my computer for about 4 days and I'm just now coming back and the microphone is not working. Pretty terrible with technology, so I will probably require some hand-holding. I don't know if this is important, but I used to be able to hear in my mic when I would blow into it and that is no longer the case. Regarding the lack of sound, nothing but Spotify appears to be creating any sound. Thanks.
