Windows 10: Audio devices in Device Manager, but not in Playback Devices

Hello everyone,

Laptop Samsung NP300V5A. Sound stops working about a month after Win 10 upgrade. No changes done at the time.

Audio devices show up under Device Manager, but not under Playback/Recording Devices. Same for Realtek Sound Manager - it doesn't see the devices. I can install, delete and update drivers under Device manager but it doesn't make any difference. It is not a physical problem, tested on Linux live CD.

Solutions tried:
-Installing various versions of HD Realtek Drivers (including windows update version)
-Installing/Removing Realtek software.
-Enabling/Disabling devices under Device Manager
-Called spirits of ancestors. Seemed like it worked for a while, but ended up being a joke.
-Did system restore to various dates.
-Restarted in safe mode
-Restarted various services such as Windows Audio, Windows Audio Endpoint Builder, Plug'n'Pray, Power, etc.
-Checked system, application and driver even logs.
-Tried a couple of registry fixes. Angered spirits of ancestors. Turning gray..
-Reinstalled chipset drivers
-Rebooted about 30 times
-Sound Device Troubleshooting finds no issues
-Display Disabled Devices is enabled

I've been looking for a solution to this issue for about a week with no result.

:)

 

No Sound After Window 10 Installation

Managed to restore sound as follows:

• Right-click on Volume tray icon to select Playback devices
• Select IDT High Definition Audio CODEC as Default Device

For some reason, USB Multimedia Audio Device disappeared as Playback device.

 

USB Audio Device showing in Device Manager but not in Playback Devices. Why?

Thank you for replying... I did try that... It did not work... My pc thinks that there is no issue...Thank you again and i hope you can solve my issue

 

By what you have done, it suggests a Windows/sound corruption. Probably going to take a Windows reinstall. Sorry.
