No Audio Output Device is Installed

[Axi]

Hi everyone,

I'm having an issue with my audio on my HP Pavilion - 15t-cs000 CTO.
After a BSoD with Stop Code: SYSTEM_PTE_MISUSE, I was left with a "No Audio Output Device is Installed."
In addition, I seem to be missing my "Sound, Video, and Game Controllers" tab in my Device Manager.
And Intel(R) Smart Sound Technology (Intel(R) SST) OED is registering a "Code 10 STATUS_DEVICE_POWER_FAILURE."

I have tried to update the drivers for this, as well as run the windows troubleshooter, utilize Recovery Manager's reinstall drivers, and run a Hardware Audio Diagnostic. All of which have refused to complete, or are stuck endlessly in some stage.

I am at a loss for what I should do next, and any help would be greatly appreciated.

Thank you all!

@Axi Have you attempted to update the BIOS, Video card & Audio drivers to resolve this issue?

While you respond to that, here's what you need to do:

Step 1: Right-click on the Start button in the taskbar area and then click Device Manager to open the same.

Step 2: In the Device Manager, expand Sound, video and game controllers.

Step 3: You should now see your audio driver name. Most likely you have Realtek High Definition Audio, Right-click on it and then click Uninstall device option.

Step 4: You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.

Restart your PC once & it should auto-reinstall a working driver.
