I have just put together my pc with some old parts, I don't have any money so got some hand me downs from friends. I have a asrock z68 extream 4 gen 3 motherboard, installed all the drivers and it works perfectly except no sound. All devices show, and the sound control panel has the green bar moving up and down on the related device to indicate audio playback. I have put an old soundblaster pci card in and that works fine so speakers are OK.
To fix I have updated bios to latest, reinstalled windows 10, updated the realtek driver from asrock website but still no sound. Is it possible that the sound chip is just dead? Or is there anything else I can try?
