My GA-MA78GM-US2H has no sound. I went to the Gigabyte website and downloaded the latest windows 7 64 bit audio drivers for my board. The drivers appeared to install correctly. I went to the device manager and everything looks fine there. In the bios the onboard audio device function is enabled. In wondows the volume levels are maxed out. If click on the speaker in the system tray I can that windows is playing the music as the sounbar fluctuates. Any ideas?
