Actually, just now tried it on https://preview.web.skype.com/ and https://web.skype.com/ and it IS working.
Not working on all sites though. Also on https://www.midomi.com/ ... Chrome works fine, while Opera at least is trying to use the mic on https://beta.midomi.com/ ... on https://midomi.com/ it says "You need to install Macromedia Flash Player." I installed it, but with no use. (I am actually with the latest Opera now, if it even matters)
Maybe it is because the mic is
HP Truevision FHD IR camera with dual array digital microphone This means it is stereo, right ? I mean it has 2 visible holes ... 
Actually they are 4 in total ... 2 at the top of the webcam and 2 by the sides.
Nevermind, thanks for the help, it's not a big deal after all.
