Hello all, I come back to you with my old question, where I got no real reply until now. Since Windows Vista, it seems the Recording device cannot provide more than 2 channels : is it a official system limitation ? is there workaround to provide for example 8 channels in a recording device (under W7/W8) ?... . And what about upcoming 5.1 microphone device ? obliged to provide several stereo input devices ? Do someone know What is the Microsoft policy there ? Thanks by advance Regards Vincent Burel www.vb-audio.com
