Hmm, there are only 2 Realtek drivers available for the XPS L702X, one from March and one from April. It is most probable that your laptop had the newest one pre-installed so there doesn't appear to be any audio driver update for Windows to install.
Whenever there are audio problems after a Windows update, you know Windows did something bad to mess up the audio but it can sometimes be hard to figure out what. You could try doing a System Restore back to before the updates. My preferred solution is to restore back to the original factory configuration, using Factory Image Restore. That will get you back to when you took it out of the box, and then turn off automatic updates and allow just security updates, not drivers, or allow one at a time and check the audio after each.
As for the Realtek site, it's about as useless as I could ever imagine a website to be. I tried looking for drivers, but there are only three audio codecs available and it doesn't even say what hardware they're for.
I have only found one available, the one from April, which is the one available from Dell and the one that Windows would like to automatically update my audio driver to. I believe my audio was like this from the very beginning before I installed said driver, although I can't remember for certain. Either way, rolling back the driver has worked fine and I'm content to wait until a new driver comes out unless someone has a more certain solution. Things are definitely not bad enough for me to want to wipe my computer clean and start over.

You could also make a restore point and try playing with the drivers directly from the realtek site in Taiwan.
It can resolve the issue but it can also make it worse.
