Audio Problem, please help!

[Choa]

Hello, for some reason the sound on my PC is no longer working. I just finished installing a cpu AIO cooler but now no matter what device I use I can not get any sound to come from PC (tried headphones and speakers). All I get is a low pitched hum sound that does not show up on the volume mixer and starts going even while the computer is still booting up.

Situation:
- PC is playing Audio (green bar shows on audio mixer) but I can not hear anything except for a low humming sound.
- Audio devices are plugged into correct ports on PC and are properly selected in device settings but no output

What I Have Tried:
- Redownloading Audio Drivers for BIOS

- Deleting and redownloading ALL audio drivers
- Tested PC audio on both headphones and speakers with no luck

- Made sure all Audio related connections on motherboard are still connected

- Made sure correct device is connected and selected in settings

I think I have now tried just about every commonly recommended solution for this problem and have had no luck at all. Please help me!!

I have checked those and they all appear to plugged in properly. Even re-seated them to make sure but I have no touched any of them prior to this issue occurring.

Oh. Welp. Have you tried plugging your headset in to every one of your jacks? I had that problem and it turns out I was plugging in my jack to the wrong outlet. Have you tried with a different headset?

I have tried every outlet with no luck, I only have one headset but have tried that alongside my USB speakers that also use the audio input jack. Both have the same issue

Do you know someone who has a soundcard? That may be the issue. Repair shops often also have them

I do not. Have never had one before and this issue is happening on a build that has been running fine for months without a sound card.

It is possible but I have no idea what would be causing this. I checked all the audio related connections and they are all still fine
