Problems with audio, brightness and HP Support assistant

HP Recommended
HP Pavilion Laptop 15-cs0xxx
Microsoft Windows 10 (64-bit)

Hello, just minutes ago my pc stopped having sound, i restarted it so maybe it could solve the problem, but the pc installed some updates for win10, in some moment when it restarted it got an error and restarted again, it was that bluescreen error with a sad face, and when it started there was no sound, the audio device could not be recognized, realtek dissappeared and the brightness could not change, staying permanently on the minimum, i tried using the support assistant, which sent me to a page that didn't work, then i search on the hp page and it said the Support assistant had an option for audio problems, which mine didn't, in which case i had to update the support assistant, and when i tried it had connection issues which sent to another HP page to download manually the assistant, but when i try to download it says it takes like 4 hours (ascending) to download a 139mb file (i dont have issues downloading anything else)

@Yvesaem Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.

That said, let's resolve one issue at a time, starting with audio:

  • Have you attempted to update the BIOS, Video card & Audio drivers to resolve this issue?
    • If not, here's the link to download and install the above updates: Click here

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.


If the issue with the sound continues, The best way to resolve the issue is by using the HP Guided Troubleshooter:
