Windows 10: No audio output device is detected and i am not able to play any audio. HELP!!!!

Product: hp omen 15-dc0045nr
Operating System: Microsoft Windows 10 (64-bit)



the speakers were working just fine before i reset my laptop.
ps: the laptop ins brand new (1 week)

reason for reseting the PC: some DLL files for DirectX were not found and i was not able to reinstall or repair it. I am running low on time for a very important project deadline so as desperate measure i reset my laptop. Now DirectX worked but now my audio doesnt work.

things that i have tried:

1)reseting the laptop again - no change whatsoever
2)trying to update the drivers
3)uninstalled the drivers and pressed scan for hardware changes - no change
4)uninstalled the drivers and tried to install the correct drives i got from hp driver support for my model - no luck
5)tried everything here: https://support.hp.com/in-en/product/omen-by-hp-15-dc0000-laptop-pc/20329817/model/24514934/document...
6)tried hp PC hardware diagnostic tool
7)install latest windows updates - no improvement
8)tried driver booster: https://www.iobit.com/en/driver-booster.php - it installed a driver under sound, video and game contollers but it did not solve anything
9)tried intel driver support assistant - no luck
10)system restore points - didnt work
11)sfc/ scannow - no integrity violations
12) i did do some other small things with luck whatsover
13)rinse and repeat all the above steps for the past 22hrs

i have some really important deadlines to make( project related to audio processing) and have my final exams in a couple of days. please can anyone save me please

No Audio Output Device is Installed

Hi,

You will need to select Windows 8 from the drop down list while installing the driver in compatibility mode.

I would suggest you to try setting the speaker as default audio output by following the steps below and check if it helps.

1. Right click on the sound icon on the right bottom corner of the taskbar.

2. Select "playback devices".

3. If "speaker" is not set as the default device, highlight it and click "set as default".

5. Save the changes.

Let us know the result.

 

Only a single audio-output device detected after latest update

Hi there,

today I installed the latest Win10 Creators Update (Spring 2018). According to my system information I am now on version 1803, Build 17134.1.

Right after the update I was no longer able to switch between my primary and secondary audio-devices (speaker and headset). Both are connected via 3.5mm jack (front and back). There is now only a single "Realtek High Definition Audio" in my list of available
devices.

My "Realtek HD Audio Manager" properly lists both audio devices correctly, but even the device manager only shows a single audio-output device.

Even reinstallation of the audio driver did not fix the issue.

How can I enable Windows to properly detect my sound devices again?
