Windows 10: microsoft uaa bus driver for high definition audio is missing from device manager

I'm running Windows 10 on a PC with an Intel i5-8400 & an ASUS Z370 mobo. The sound quality was rather flat, so I proceeded to tweak it with the equalizer setting, whereupon I noticed that the Realtek HD audio drivers were actually missing. I installed these but afterwards, the associated icons did not appear anywhere on the taskbar. I couldn't open RtkNGUI64.exe manually either. So I tried to follow the suggested steps on fixing this issue, but when I opened the device manager, I couldn't find Microsoft UAA Bus Driver for High Definition Audio under system devices or anywhere else.


It doesn't seem to be available at Asus, so where do I download this?



Thanks in advance.

Realtek Audio Drivers messed up - Microsoft UAA?

I would try this first: http://drivers.softpedia.com/get/SO...AA-Bus-Driver-for-High-Definition-Audio.shtml but uninstall your audio driver first, reboot, then install this M$ UAA driver. That is very strange that the realtek drivers didn't install this if its a HD audio chipset, I 've done it so many times at work it is basically routine. If that doesn't help there could be a driver conflict from the previous audio driver still trying to find its chipset which in turn is causing problems with the realtek not working.

 

Realtek Audio Drivers messed up - Microsoft UAA?

I installed a new motherboard ASUS P5K-SE to replace an ASUS P5N32E-SLI that died. The P5N32E-SLI had an Analog Devices sound chip but the P5K-SE has a Realtek chip. When I booted up into Windows the first time it installed all of the drivers required for the new board but the sound would not work. I checked in the device manager and there was one device that had a yellow exclamation mark "microsoft uaa bus driver for high definition audio".

I tried installing the Realtek drivers from the provided ASUS CD and also downloaded the latest drivers from ASUS (which I think were the same version). I tried manually updating driver on this one device but it can not find the driver files. At one point I was so frustrated I just deleted the device from the device manager and rebooted. This time it found a device called "PCI Device" (how helpful) and I can not find proper drivers for it anywhere. If I open the properties tab for the device and look at "device instance ID" it shows

PCI\VEN_8086&DEV_293E&SUBSYS_829F1043&REV_02\3&11583659&0&D8

When I search on the topic I find people with the same issue and the solution always seems to be that this Microsoft UAA Driver is included in the Realtek drivers but it doesn't seem to be working for me. Ay suggestions?

I have that same board but, unfortunately, never used the HD audio built in.

Have you tried visiting the P5K-SE Asus download page to check for newer versions of those drivers?

EDIT

It seems i skipped an entire paragraph of your post *Frown

Still, try downloading just the HD audio drivers, uninstall that PCI thing you mentioned and reboot. When it find's the "new hardware", point it to the HD audio drivers folder.
