Ok I`ve been having a lot of problems trying to get an hdmi audio driver to work.I just got a sapphire radeon hd 4830 with built in hdmi port.I installed drivers from the disk and it worked at first but now if I restart I either get a code 10 device cannot start or blue screen of death.I`ve tried updating the drivers to ati function driver for hd audio still no luck. I even went into bios turned off onboard hd audio or set it from auto to enabled and still same problems.Going crazy with this!Anyone can help please. system: AMD athlon 4850e 2.5mhz biostar ta790gx mobo 4g gskill 800 640 wd sata hd
What version of Windows are you using? Try and uninstall the drivers, reboot and installl from disk again, this is to make sure you didn't install Windows update drivers and that cause the problem.
