New win. 10 install, no audio output. device installed.

Hi!
I am brand new to this forum, and not a big computer geek.
I just got back my HP Pavallion from a shop that upgraded my Vista to Win.10, and my memory from 2GB. to 8GB.
My problem is I have no sound now, the sound icon has a big red X next to it, and when I hover the cursor over it it says; "No audio output device is installed"
I am using two HP multi media compact speakers that worked fine with the Vista.

In my device manager, I found four drivers listed under sound, video and game controllers, all of them have the same name, NIVIDIA High Definition audio.
I thought the sound drivers were supposed to be realteck.
should I uninstall all four of these NIVIDIA drivers, and restart the computer?

I don't want to have to go back to the shop, they had it for a week.

Thanks for any help.

Get the latest one (R2.81) from RealTek for your build 32 or 64 bit.
Realtek

Considering it was upgraded from Vista, the sound hardware that is on the motherboard may not be Win 10 compatible. Usually, if the sound hardware is compatible either Windows will install the correct hardware driver or at minimum install the generic High Definition Audio Codec (driver). As neither was installed it could be an incompatible device.

Don't uninstall the nVidia drivers. They get installed with your display driver and are used for HDMI.
But there should be just 1 for that. I don't know what the others could be.
Can you post a screenshot of Device Manager with the Sound category expanded?

What you probably need is a Realtek driver. Have you looked on the HP webpage for your PC to see if there is one listed there that you can download and install?

Don't know how to do screenshots, but the expanded sound category looks like this:

Sound,video, and game controllers
NAVDIA high definition audio
NAVADIA high definition audio
NAVADIA high definition audio
NAVADIA high definition audio
Seems to be four drivers for the same thing.

Well I did this, downloaded and installed the 64 bit version on my machine, didn't work, there isn't even any sign of the realtek anywhere on my computer, its not in the device manager, and the speaker icon still says no audio output device is installed, I restarted it twice.

Hmm ... No RealTek HD Audio Manager in Control Panel ?

If you haven't already, check BIOS to see if sound is enable and in Device Manager / View / Show Hidden Devices to see if you see any warnings. If no issues there, try going to Settings / Update & Security / Troubleshoot / Playing Audio and run it.

I did a search for the HP model that the user has listed. I didn't find any drivers listed later than Vista. In most cases at a minimum Windows 8.1 drivers are needed for Win 10. Vista/Win 7/Win 8 are usually not compatible.

As I mentioned on my earlier post, the sound device may not be Win 10 compatible. Its a Celeron CPU and MAX 2GB of RAM. I'm surprised it even runs Win 10.
