You have upgraded a machine that Dell states they did not test for Windows 10 and for which they are not developing drivers. That doesn't mean all hope is lost, but it might be. I had to give up on an Inspiron 1720 that I could never find a mouse pad driver for that worked under Windows 10.
That being said, see the audio driver section of the Dell Support Page for the Studio 1535. There is a driver for your audio card issued by them with a 2011 latest update date. That may fix your problem, but it may not. It's a good place to start, though. Under device manager I would uninstall the Microsoft driver first, then uninstall the device entirely, then try using the driver from Dell.
As you've now learned, Device Manager reporting that a device is running normally does not necessarily mean it is. I have yet to see the converse: reporting that something is not running normally but the device is functioning anyway.

I have no idea why you have 2 properties screens, that might be the start of the problem.
Sound is one of the main problems with Win 10.
Go to Dev Mgr, Sound and uninstall all (if you have 2 properties, you have 2 installed) HD Audio you're using. Restart and let windows find the correct one. It may take several times.
If that doesn't work, back to Dev Mgr, click on the top listing for for your PC. Click Action, Scan for new hardware.
If that doesn't work, Action, Add legacy hardware.
If that doesn't work, install the Dell driver again, only if you have an IHT HD Audio. Sound drivers are exactly what you say you have. They are generic MS drivers.
If all this doesn't work you're in for a reinstall.

Something to try:
Try uninstalling all audio drivers/ delete driver files. You should have a folder where the dell setup unzipped to. Usually C:/dell/. Also uninstall anything from add remove programs if there is something there.
Find the folder with the audio driver setup files and try setting compatibility to windows 7, and run as admin/reboot when finished. I don't think you need to reinstall the OS. Sometimes audio drivers can be tough to get right. You could also try to install the chipset drivers from dell.
