Windows 10: Realtek Audio NOT Working? [WINDOWS 10]

So this has been an issue for a while now,
Every time I try and install 'Realtek HD Audio Drivers', My PC doesn't install them, and says it's the drivers aren't compatible. In the sound tab in the taskbar, the 'speakers' don't show up anywhere because Realtek isn't installed. Whenever I go to device manager, under Sound, video, game controllers, It says 'NVIDIA High Definition Audio'. This is a PROBLEM as when I am making music, the volume is pretty LOW and slightly distorted, even when everything is at 100%. My laptop which also runs Windows 10, and Realtek is installed and working on that. When I used Windows 7 before I upgraded to Windows 10 64 bit for my PC, Realtek was installed and also worked fine on that. [could it be a sound card issue?]

I am currently running a HDMI cable from the screen into my graphics card, and the AUX cord from the Sub [and speakers] into the back of my screen. The sound works at the moment but the problem is that the volume is very LOW. I have tried enabling Loudness Equalization in the enhancement tab in the sound options [in the taskbar] and nothing made a difference, I have also tried running the AUX cable into the motherboard and sound card from the Sub, but no sound comes through.

Here are also pictures that show what the problems are.

No audio from rear I/O audio connection in motherboard panel

I am not able to get any signal to the rear audio jacks of my Sabertooth Z97 Mark 1 Mobo, I am running a licensed version of windows 10 pro x64bit. My speakers are the BOSE Companion 50 with the standard 3.5mm jack. I updated the drivers to the latest Realtek
HD Audio drivers but to no avail.

There are 4 audio devices in device manager

2 in "Audio inputs and outputs"

- Realtek digital output (Realtek High Definition Audio)

- Realtek digital output (optical) (Realtek High Definition Audio)

and 2 in "Sound, Video and Game Controllers"

- High Definition audio device

- Realtek High definition audio

AND...when I plug my speakers into the front chassis HD Audio output.... 3.5mm headphone jack...the sound works fine. (this is plugged into the Front Panel Audio connector (10-1 pin AAFP) on the motherboard.) When this is plugged in,

a 'speakers (realtek high definition audio)'

device appears in the "Audio inputs and outputs" in device manger.

When I plug the speakers into the rear mobo I/O Audio connection, there is recognition from the Asus Realtek HD Audio software that something has been connected, but no sound is output through them at all. I have changed the playback devices to both realtek
audio and realtek audio (optical), from what I understand, the 'Optical' is the optical output from my motherboard that is labelled SPDIF out on the rear panel? Is that right?

I just don't know what else to try.

Its worth mentioning I only built this PC last weekend and so have never had any audio signal from the rear of this motherboard.

Any suggestions would be appreciated.

 

Unable to upgrade from Windows 10 1703 to 1709

There is no Card Reader in the Device Manager anywhere.

Regarding software, I ran regedit and searched for "realtek" and the only results I could find in the entire registry were either a) the Realtek Audio and b) the Realtek FE controller (wired internet).

If there was software, it is supposed to be in c:\program files\realtek but the only folder there is Audio,

 

Is this an OEM PC or a custom build? If an OEM....need the brand/make/model of it. If a custom built PC....need the complete system specs.

 

I bought it off a friend 4 years ago, i think it's custom built

Processor: Intel (R) Core (TM) 17-3770 CPU @ 3.40GHz
System Model: To Be Filled By O.E.M
System manufacturer: To Be Filled By O.E.M
Motherboard: ASROCK z77m
Graphics Card: NVIDIA GeForce GTX 760
System type: 64 bit, 65x Processor
RAM: 8gb

 

Great.....now....what bit is your OS...32 or 64?

 

You can download your mobo sound driver directly from ASRock.......just pick your OS and bit type.

ASRock > Z77M

 

Are you sure, you have Realtek audio? For the record, you can find the latest drivers here:

Download Realtek HD Audio Driver 6.0.1.7936 for Windows 10, Windows 10 64 bit

I am using an ASRock Z77 Professional Fatal1ty motherboard (using the same i7 3770 CPU). It has Realtek and is Win 10 compatible, using the Realtek drivers direct from Realtek.

However, if you are using HDMI audio, then that is generated in the NVIDIA Video Card, not from Realtek.

I have a recording studio (Sonar). I wonder if the Akai synthstation is causing any conflicts. Temporarily disable that and see what happens.
