My Audio Service refuses to function properly. I have tried so many different solutions I can't even recall all of them.

Here's how it started; I got home from work one day to see my computer has no video signal but is turned on and receiving input from my mouse/keyboard. I force restart my computer and, after it boots up, I see that the Windows Audio Service is stopped.

I first try to use the task manager to start the service (Audiosrv) and it would blink at Starting then immediately go back to Stopped. From here I went to the Services window and tried starting it from there (Windows Audio) and, after trying to start, says Access Denied (Error 0x80070005).

So after searching a solution I went into regedit and was told to add System as a permission group for AudioSrv and the AudioEndpointBreaker service. Turns out they were already there with FULL CONTROL for both.

I try to change the logon to use Local System Account (WITH INTERACT DESKTOP CHECKED!) and voila, my audio service is running! But my bad luck continues.

None of my speakers/headphones are creating sound even though the service turned on and I can see all my devices. As an attempt I tried to do test sound, and this error appears.

Keep in mind I've restarted after every one of these fixes, both the service and my computer afterwards. As a final attempt I tried to open the Command Prompt as administrator and entered sfc /scannow . After verifying, this message appears.

I honestly have no clue what could've happened while I was working, but I'd rather not have to reinstall my windows to lose all my files.

Recap of my attempts to solve

1. Start the Audiosrv service from Task Manager (failed to start but keep in mind the EndpointBreaker service was running)
2. Opened services window and tried starting the Windows Audio service (Access Denied [Error 0x80070005])
3. Tried adding System as permission group for AudioSrv and AudioEndpointBreaker to find out both already had Administrators, my user, and System with full Control.
4. Changed login to local system account with interact desktop control checked and it fixed! Supposedly. THIS WAS THE FIX FOR 99% OF PEOPLE ON THE FORUMS
5. After realizing my sound wasn't playing but my devices/control was showing up, tried testing sound and received an error.
6. Last resort I did a sfc /scannow command and was given the response shown above.

What should and what can I do to get my audio running?

SIDENOTE

When I drag the volume slider [which usually creates a tone with the volume adjusted], the speakers/headphones meter on the Sound window do NOT light up green (in other words they aren't showing sound receiving on its end)

I resolved this issue after doing a system restore.
