I just update my amd graphics Card driver and audio not working.
They not show AMD HIGH DEFINITION SOUND anywhere.
A320 motherboard from msi
i have a similar problem sometimes. i have an onboard sound card but i have that disabled in bios and i have a sounblaster audigy fx for my sound. sometimes when i update the graphics drivers, the soundcard doesnt produce any sounds at all. the drivers are there, from the look of it it should work but it doesnt.
what i do is this:
hope this could help
