Hi,

I've had my computer from Overclockers for about 2 years with no issues, but now my sound has stopped working.

I have the Z370 AORUS Gaming 7 montherboard that has Realtek onboard sound. I've tried re-installing the drivers with no success and have checked the BIOS to ensure sound is enabled.

When I view Device Manager it does not show the Realtek device and does not find it when I search for hardware changes.

You can see in the below that one of the "High Definition Audio Controller" has the exclamation marks on it, but when I update drive on it states it has the best driver for the device installed. If I navigate to the driver files I downloaded it states the same.

Any help would be appreciated!

Thanks.
 
The one with exclamation mark
Try roll back driver option
If it's not greyed out
Greyed out means you can't obviously

In that case use uninstall driver option
Making sure to tick delete this driver
Then install the 1st driver for realtek on motherboard makers website

By running the downloaded program
Not by browsing from device
Manager
 
Thanks for the response. I Uninstalled Device, ran the Realtek Driver install, restarted and the device comes back with same error. In device status it has:

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

I Googled and have already tried fixes I can find for this.

In events I see the following:

Device PCI\VEN_8086&DEV_A2F0&SUBSYS_A0C11458&REV_00\3&11583659&1&FB had a problem starting.

Driver Name: hdaudbus.inf
Class Guid: {4d36e97d-e325-11ce-bfc1-08002be10318}
Service: HDAudBus
Lower Filters:
Upper Filters:
Problem: 0xA
Problem Status: 0xC0000001

But no idea what that really means :)

My concern is that Realtek isn't showing under "Sound, video and game controllers", I'm sure it always used to show there and I'm starting to think this may be a hardware issue.

have had loads of problems in the past with realtek
every one ended up being software though
is realtek showing in add /remove programs?
if so uninstall it
restart pc then install version from motherboard manufacturer
 
do you happen to have system restore turned on?
if so restore back to when it worked

if not could try uninstalling it again
and using one of those driver updaters
or try windows update
though obliviously manufacturers driver was first choice

rarely hear of onboard sound actual hardware failure is the good news
another option
to double check rather than waste hours
is boot off a live cd/dvd/usb
windows or linux
if sound works there its definitely a software issue
 
*** FIXED ***

I'm not actually sure how I fixed this, but this is what I done...

Cleaned computer, I don't think this done anything apart from remove dust!

I then uninstalled drivers, downloaded drivers again from manufacturer site and installed. Much to my amazement this then showed Realtek in device manager after restart. However everything I tried I could not get the sound to work.

I then uninstalled the driver again and restarted, when Windows loaded I heard sound, tested and it's all working. Now in device manager it does not have Realtek, but does have "High Definition Audio Device" under "Sound, video and game controllers".

I could try installing the Realtek drivers again, but for now I think I'm going to leave it as fixed :)

Thanks for the support

You're welcome
And was pretty confident it wouldn't be the hardware
It's possibly because each board manufacturer adds their own stuff
To realtek drivers
Asus for example shove sonic suite and studio in
 
Glad you got this sorted out, I just wanted to report I had a similar issue with on board Realtek for a Z390 ROG Strix.

The Realtek driver worked fine for a year or so, then a couple of weeks back while on headphones I got a drink and returned to find the sound just completely gone, no explanation.

Uninstalling Realtek drivers and restarting did the same fix as you've ended up with - sound working great but listed as High Definition Audio Device, not Realtek.

Reinstalling Realtek drivers again makes the sound go away again, so like you, I'll be staying as I am.

I'm pretty sure a Windows update broke their drivers and they're too slow to sort it out.

Other than that I'm 100% it's a software issue rather than a hardware one that can be most likely be blamed on Realtek's out of date drivers.
