Running on an MSI GE73 Raider RGB 8RF and the sound just randomly stopped working a day after I plugged in a second monitor. Worked fine the day before, now the volume icon has got an "X" through it indicating no sound devices are available. I'm completely at the end of my rope. I just finished a manual file backup and I'm about to restore my laptop. I'm just going to ask on here as a last ditch to see if someone has some answers for me.
Things I've tried:
Performed a driver search, nothing came up audio wise as being outdated
Used Windows Sound Troubleshooter, came up with nothing
Reinstalling Realtek drivers (Realtek won't show up no matter what I do after install, not in Control Panel, not in Device Manager, and not as an audio driver)
Reinstalling legacy audio drivers via Device Manager - Met with a BSOD if I try to install any Realtek legacy drivers (RTKVHD64.sys causes a BSOD when this happens)
I have two entries for High Definition Audio Controller under "System devices" in Device Manager. One with an error on it, the other is fine. One seems to do nothing, uninstalling/disabling it and reinstalling it is met with the same error icon indicated with a code 10
"Sound, video and game controllers" I only have "NVIDIA High Definition Audio" which is the HDMI passthrough to the monitor, but I don't want sound coming from the HDMI so when I disable it, nothing shows up there.
I reinstalled any support files off of the manufacturer's website, but they were just Realtek audio drivers which had the same effect as before.
Updated NVIDIA Drivers
Updated Windows
Tested with headphones, ASIO audio drivers, laptop speakers, got nothing.
Restore point failed

Is there an entry for the onboard audio in the BIOS? Maybe toggling it to enabled/disabled would make it come back.
Try checking for any realtek drivers using "pnputil -e" (https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/pnputil). If you can find any audio drivers in the list, try using "pnputil -d oem#.inf" to get rid of them, then reboot.
I had a very similar issue happen to me a year or so ago. I had come to the conclusion that a windows 10 update had blown away a specific sound driver. I remember that installing realtek drivers seemly did nothing. It wasn’t until I found a freeware driver scanning tool, that it told me I was missing the specific sound driver. The tool wanted me to pay for it to auto fix it but eventually I was able to find one that would download the driver file for you but wanted you to pay for it to install it. So i used that to download the driver and then manually installed the driver and I haven’t had any problems since.
I went through a similar process and it seemed to have worked. Windows update was definitely the cause of it. So bizarre, just completely deleted Realtek and any audio drivers off my system.
