(my current sound panel)
Hello,
I have recently installed Windows 10 on my iMac (27-inch, Late 2013.) I have successfully gotten the internet to work, but not the sound. I have upgraded and installed the newest Bootcamp software, but still, nothing. I have watched repeated videos, yet, nothing has happened sound wise. I've tried putting in headphones and that doesn't help. Any answers/tips?

Before you go through an entire re-installation, can you run these in the current state and check once more for unknown Devices. This may save you a full re-installation.
I do not have Cirrus audio device. Instead, I have NVIDA audio devices installed.
You do not need to run the 'sudo' command, since you have posted the msinfo32 information. Your installation is correct. You should have a Cirrus audio device. Can you go back to Device Manager and post a screen shot? On a W8.1/2012 MBP, I have...
... and the drivers are....
You can use BC Assistant and download BC6 drivers to a USB Flash drive using
Once you have the USB with drivers, switch to Windows and run setup.exe from the Bootcamp folder. Also run Apple Software Update on the Windows side, after setup.exe completes.
From Identify the model of your iMac - Apple Support, your iMac is a 2012 machine. These are preUEFI machines and do not support EFI Boot properly. The Audio devices are exposed using CSM-BIOS layer, which requires a legacy BIOS installation. Can you post the output of the following OSX Terminal command?
sudo fdisk /dev/disk0
If you have more than one entry, then you have a BIOS installation. You can also run msinfo32 on the Windows side and check BIOS Mode. If it is UEFI, then your Audio will not work. Unfortunately, you will need to re-install Windows, if it is not the correct installation type.
How much effort is it to re-install Windows using EFI Boot? Please also check if there are any pending firmware updates using for your specific model in About EFI and SMC firmware updates for Intel-based Mac computers - Apple Support .
Sorry for not replying to you earlier, and by the way thanks with all your help so far. I appreciate it.
The following is from the terminal;

Carlini is not in the sudoers file. This incident will be reported.
Carlini is the name of my Mac. I will get back to you on the Windows side soon.
This is from a 2013 rMBP (Intel / nVidia GT750m) running W10. I have both nVidia and Cirrus. Your display should look very similar.
There are some similarities, but not many. Should I just try downloading sound drivers for the NVIDIA Drivers?
I don't know how to really say this, but I don't think I will get sound on my Windows partition. Please understand that if I happen to mess something up software wise, then I won't hear the end of it from my family. Our family all shares the computer, but I happen to use it the most. I am fairly new to dual booting and sorts, so I don't have much confidence in my skills in this topic. Thank you for helping me. I appreciate it.
We are not modifying the OS X side. If you are not comfortable, you may want to just try these two and avoid a full re-installation. These two procedures do not change software, but rebuild the underlying hardware resources. You may be able to see missing devices. Also, you have some unknown devices on Windows side, which requires Bootcamp drivers to be re-installed.
In Device Manager -> Audio, do you see any devices? Are there any unknown devices? Also, in Device Manager, under View, check Show Hidden Devices and check.
All I see is Digital Audio (S/PDIF) (High Definition Audio Device) and Headphones (High Definition Audio Device)
with the 'Show hidden devices' on.
Was Windows installed using BIOS or EFI Boot? Can you post the About This Mac -> System Report -> Hardware -> Mac Model Identifier?
Model Identifier: iMac13,1
I'm pretty sure I did EFI Boot, although I could be wrong.
