I have an ASUS M5A78L-M + USB3 motherboard and the Rosewill Ranger-M case. The computer plays sound through the hdmi attached tv but that's it. I've been needing to use a microphone (I've tried like 8 headsets) and I just can't. All the ports pick up the device, and recognize a SMALL amount of sound coming from the headphone itself, but never through the microphone. Apparently it uses VIA drivers, which are supposedly all up to date. I searched online for drivers and used the CD that came with the MOBO but nothing happens when I try downloading any of the VIA drivers from the CD, and half of the drivers on the CD don't work as I get this error: WNT_6.2H_64. I am at my wits end with this ordeal and feel like I won't ever be able to use a microphone or any headphones with this computer.
