So I have speakers hooked up to the 3.5mm jack on the monitor and it outputs sound when my nintendo switch is connected (via HDMI) but not on my pc (via DP) any ideas?

In the sound control panel I have my normal headphones, Speakers Realtek USB Audio (says "not plugged in"), Headphones Realtek USB Audio (says "not plugged in"), Realtek Digital Output, Sonic Studio Virtual Mixer, Speakers for Yeti classic (The mic but I don't know why it shows up as speakers as well

Any help would be appreciated

In system devices I have 2 "broken" audio controllers

But it's weird that nvidia doesn't allow a HD audio driver install maybe because they discontinued it in win 11? i have no idea

If it's disabled or broken in Windows the option won't show up in the driver. I'm fairly confident your problem is exactly that. You could start by removing them and also checking for any hidden devices in there which match either nvidia high definition audio or just high definition audio and remove those as well.

Showing hidden devices in device manager shows "Nvidia Virtual Audio Device (Wave Extensible) (WDM)" in sound,video and game controllers but nothing in audio inputs and outputs
 
There may be two issues here, but description is not entirely clear.

First, a fundamental issue. You probably have at least TWO different ways for your system to send out audio. Your moboi has a Realtek audio output system that sends out signals via 3.5mm sockets on the mobo back panel. I expect that you also have a video card in a PCIe slot. Now, there is no way for an added video card to get an audio signal from a mobo Realtek system. So virtually all video cards have their own second audio chip on them, and very often when that card is first installed it sets itself up to send audio out through that card, and not through the mobo back panel.

But Windows can use only ONE audio output system at any time. YOU can change which output system Windows uses, and then YOU must ensure the correct output line is connected to your speakers. At bottom left type into the search window "sound settings", then let it open that window. The first item is the Default Sound Output device. Use the drop-down chooser to see what devices you have, and I be there are a Realtek system PLUS a system named like your video card. If you choose to use the video card system, then all audio output will come from that card and its ports. Both HDMI and DP ports can and do carry audio with them. So at your MONITOR if it is set to use audio from that video cable input it will work. BUT you say you have a separate cable from your MOBO back panel 3.5mm socket to the monitor. So if your monitor is set to use that input line for its audio signal, it is NOT getting anything if your system is set to send sound from the video card! Because you say the Realtek system reports there is nothing attached to it, that may be how your system is operating. So one option for you is to set the MONITOR to get sound from the video input cable and NOT try to use the separate sound cable.

On the other hand, IF you really want to use the mobo Realtek output system and its rear panel 3.5 mm socket, then in that Windows Sound Output screen you can select that. THEN you can set your MONITOR to use the separate audio cable from the mobo back panel into the monitor' audio input socket.

Second possible issue. You mention the "Realtek Digital Output" option in that system, and that may show up also in the Windows Sound Output screen as a choice. "Digital output" on an audio system often means output via an OPTICAL fibre port intended to go to an external amplfier, so it does NOT sent audio out through the 3.5 mm socket. IF you have chosen that Digital Output, change that in the Relatek system to use the Speaker output - that is the 3.5 mm socket.

I don't have anything plugged into my mobo rear audio jacks (I have wireless headphones and speakers are plugged directly into monitor), no sound output device remotely resembles a nvidia device/monitor. I believe the error lies somewhere with the fact that I don't have/ can't install nvidia hd audio drivers
 
So you have and use a video card built with nVidea hardware, installed in a PCIe slot. and yet you cannot find ANY nVidea device driver installed? Not for Video OR Audio? I presume you are looking for that in Device Manager, right?

And yet you are using that to feed the monitor, right? The monitor is NOT being fed from a port on the back panel of your mobo? This can work if Windows is simply using a generic video driver because it cannot find the "right" one. But if that really is the case, try Tech Support from your graphics card maker.

im using a 3090 with driver 560.70 (latest) when I use the custom installation tool the hd audio driver cannot be seen which means it is not read. I believe it is due to these two "broken" hd audio controllers in device manager https://postimg.cc/bDgV4cg6 and https://postlmg.cc/cKQbM8nG which i think is the nvidia drivers but are unable to start for whatever reason
 
I do not know why there are TWO audio drivers installed, or whether that is wrong to have. The only path forward I can suggest is to remove ALL the drivers associated with the video card and let Windows discover they are missing and re-install. To do that follow this sequence.

1. At lower left type in Device Manager to get that window.
2. Expand the Display Adapters and right-click the entry for your video card. Choose to Uninstall the device.
2. Now expand the Sound, Video and Game Controllers. Find all the drivers for the video card sound system and use right-clicks to select Uninstall for all of them. You do not need to un-install any driver for the mobo Reatek system.
3. Back out to main screen and reboot your system. It will boot up, find no drivers for those devices, and use a default plain video driver to start up, so your screen may not look normal.
4. Windows then should pop up on screen a window saying it has discovered a new device and is installing its driver - probably the video card system first. Then it should do that again for the audio system on that card. That is probably all the "new devices" it will find.
5. When it is finished, reboot your system again so it will start to use the re-installed drivers. You may have to re-adjust your video display settings to get your screen back to how you are used to it.
6. You may still have no sound from your monitor via the video card's system because Windows has re-set itself to using the Realtek audio system on your mobo. Just to be sure about this so far, go back into Device Manger and check for drivers installed for Video and Sound. The two drivers you need should be there with NO yellow Caution triangles. If either is missing, RIGHT-click on the very top line of the Device manger list and choose Scan for Hardware Changes. This will force it to re-scan and discover any devices that do not have a driver, and install one. Then re-check the devices (maybe the sound system list) to verify that the driver you expected to see it now there.
7. Once you are satisfied the drivers are installed cleanly, back out of Device Manger. Now type Sound Settings into the bottom left search slot to get there. Use the Default Sound Output section at the top to tell it to use the sound system on your video card. Now go down to almost the bottom and choose Sound Control Panel to open that. Click on the main playback device and then on Configure at lower left. Choose the right output device (speakers on your monitor) and click on the Test item to see if they work.
8. Assuming that does work, back out of the Sound Settings system to main screen. Just to be sure, reboot again.
