i tried to install the hda onboard driver manually but appears "the audio driver files do not support your computer hardware", uninstalling amd hda just wasting my time.
 
If The sound card is under device manager then it on.most times with older mb and mad cards the amd sound chipset becomes the main audio output. You should be able to go under sound. Output devices and disable amd hdmi audio output to get your sound back.
