What has the Graphics card got to do with sound? Uninstall audio drivers, restart, install latest ones. Check if the speaker is plugged in all the way.

Did you get a fix? The installer adds HDMI sound for the card and removes existing sound config. Go into the BIOS and if sound set to Auto, set to Enable, save & reboot. Or if already set to Enable, Disable & reboot, back to BIOS, Enable, save & reboot.

Worked for me - I'd re-installed Realtek drivers about 3 times with no luck.
