Optiplex 780 Audio Driver Windows 10

Since I upgrade to Windows 10 (coming from 8.1) in my friend's Dell Optiplex 3011 All-In-One computer, with built-in speakers, the audio has been disabled, and I see the Windows speaker icon is with an 'x'. In Windows 8.1, the audio was working normally, so it's not a hardware issue. However, if I plug in an earphone, the audio output is enabled and the Windows speaker icon changes to normal one. I installed the latest version of Realtek HD Audio driver (R2.79), and restarted, but the audio continues disabled unless an earphone is connected. I first upgraded to Windows 10 and installed the Realtek audio drivers. Then, I performed did a clean install and installed the Realtek audio driver again, but audio is still disabled.

When I open the Realtek Audio Manager in Control Panel, only the microphone tab appears. When I plug an earphone, the speaker/earphone tab is visible as it should be, disappearing after I unplug it. I reinstalled Windows 8.1 in his system hoping to have audio working again, but the problem persists. Amd Radeon Hd 5800 Series Driver Windows 10. I've tried installing the Realtek HD Audio driver from Dell supporte page for my product (entering the service tag to be 100% sure), but no luck. Windows troubleshooting is useless as usual, not giving any help, only asking me to plug in an earphone, like I didn't know it.

I even upgraded Dell BIOS/UEFI firmware to latest version (A07), but it didn't fix anything. Does anyone know how to solve this problem? Thanks in advance.
