VIA audio HDMI Windows 10 No sound. Z77X UD3H

VIA audio HDMI Windows 10 No sound. Z77X UD3H
« on: June 23, 2017, 04:48:07 pm »
So, everything was fine yesterday. And I haven't installed anything recently. And this morning my PC has no sound with the motherboard hdmi audio. Windows detects the driver and I can see it in the audio options, but when I try to configure it to my setup (5.1 speakers) it freezes and then says 'device not supported'. If I leave it to the default 'stereo' it still doesnt play a sound. I tried uninstalling the VIA driver and installing it again (latest one) but it didn't work. Not sure what to do. I've also noticed that all my steam games wont start, it gives a 'error 80 code' on steam. Not sure if related. Any help would be greatly appreciated.

ok, so I deleted both VIA and Intel audio drivers; then Windows downloaded some generic 'high def audio driver', and now it works. sigh.

But with this new generic driver from Windows I'm not getting Dolby True HD and DTS HD, just lossy audio. And if I try to change the bit output to 24 bit it crashes the audio. Also, when installing the VIA drivers again, it does nothing. It doesn't show up or anything. I'm stuck with the windows driver atm. Jeez.

Ok, i figure it out. I didn't have to install the VIA drivers for HDMI audio, but Intel's (R) Display Audio drivers, that come with Intel's Graphic's drivers. But if you delete Intel's graphic's drivers and let Windows do a clean installation, it doesn't install the audio drivers if you already have a Windows generic audio driver for HDMI. So you have to go Intel's website and manually download and install the drivers to get the full package. Now I have Intel's Display Audio driver,  and Dolby True HD and DTS HD are both working, finally. No idea what happened, probably Windows 10 updated something and corrupted my audio driver or something.

Good work solving your problem.  The issue was likely between the older VIA drivers and newer Intel Graphics w/ HD Audio no longer being compatible.  VIA was a great company, known for their north+southbridge chipsets, RAID, Audio and FW controllers..  They ruled the 90's and were a staple on many of the AMD boards I owned.  If you have the dolby function with the newer drivers, there's no need trying to get the VIA drivers to work with W10.  8)
