This is for information, but I can't take the time to write a 30 page "how-to" manual.
I had a significant problem with a new XPS 8930 purchased recently. The audio jacks, both rear and front, were not working properly. If you unplugged speaker or headphone, Windows would red-X the speaker symbol in the system tray and audio quit working. If you plugged it back in Windows would not re-enable the device. If you plugged in headphones the system would not auto-switch from speaker to headphones. The only fix was to go into device manager, open the RealTek HD audio device, disable it, then re-enable it, and the speakers (or headphones) would work again. The alternative was to restart the PC.
The problem seems to be faulty RealTek HD audio driver version 220.127.116.1148 that came installed on the XPS. I downloaded version RealTek HD Audio R282 driver pack from RealTek, unplugged my Ethernet cable, uninstalled the existing drivers in device manager (with delete checked), installed the down-level drivers which now show up as version 18.104.22.16886
Then I went into group policy editor, Computer Configuration, Administrative Templates, System, Device Installation, Device Installation Restrictions - and enabled the policy "Prevent installations of devices that match any of these device IDs", and configured it with the RealTek HD audio hardware IDs obtained from device manager. Those IDs for my system are:
I believe this will prevent Windows from automatically "upgrading" drivers for this device.
Now everything audio seems to work properly. A side benefit is that the Maxx Audio (IMHO useless bloatware junk) is gone. The R282 driver pack directly downloaded from RealTek does not include the Maxx software. After going back online and checking for Windows Updates, the drivers I just installed were not replaced - thank goodness.
Sorry, this is just a synopsis, and I can't take the time to write a detailed how-to. Perhaps it will allow some Dell customers to fix their similar problem, and give Dell Support a clue also - so they can, perhaps, decide to release a driver fix.
Best of luck.
Since the changes to the realtek are based on security I would not recommend this ever.
CVE-2019-19705, the vulnerability could be leveraged to evade defenses and achieve persistence by loading an arbitrary, unsigned DLL into a signed process.An attacker targeting the vulnerability could load and execute malicious payloads within the context of the Realtek signed process. Windows Defender Application Control and Windows and OEM driver updates are issued to block known vulnerable software and drivers.
The full detailed description of the Realtek Audio Driver update version 22.214.171.12448 does not mention anything about it being a security update. The description only mentions supporting Windows 10 Fall Creators Update. The Importance of the update is Recommended. If the driver update was security related then usually the Importance is Urgent.
that statement is in complete denial
Realtek Audio Drivers for Windows –DLL preloading and potential Abuses
Security Risk High
Patch Legacy (non-DCH) driver
With Realtek High Definition Audio driver, the local user is able to gain privileges via a crafted DLL in the same folder as the running executable file. The root cause is that Microsoft Visual Studio 2005 MFC is used in the named driver package which automatically loads a resource DLL. The VS2005 MFCuses a low-level function Ldr Load Library that also loads a code section, and thus there is a potential risk that unexpected code may be loaded.
Microsoft is changing the way that hardware drivers work on the Universal Windows Platform (UWP), Windows® 10 (and later), and Microsoft Windows* Server 2019 (and later). Hardware running on these operating systems can use Windows DCH Drivers.
As of November 2018, driver updates will begin transitioning to Windows DCH Drivers. After a driver has been updated to a Windows DCH Driver, it's possible to roll back to a legacy driver; however, rolling back isn't recommended as it can expose the user to security issues.

Saying that the driver is old and that there is a potential security issue doesn't offer much of a solution to the OP's problem. The old driver didn't work for the OP anyway, but he found a solution. Hopefully, this can help someone else with this problem until a new driver becomes available.
I would be perfectly enthused if you could recommend a driver package that 1) works, and 2) has the latest security fixes.
That "very old" 126.96.36.19948 version you mentioned is the one that arrived from Dell, in a new machine delivered a week ago. What's a customer to do? The customer will wait for Dell to publish an updated driver package, that's what, and if said customer is technically savvy he might find a temporary work-around.
I would have done exactly what you did, find a work-around. The alternative is no working audio jacks. I am a little surprised that I have not seen this problem reported here.
I apologize for writing on different topics.
I am having a problem with dell 5448 battery not being charged. The white led on the computer lights up when the power adapter is plugged in without the battery. the white light turns off when I insert the battery and plug in the power adapter.
I suspect the battery, paying $ 110 and bought a new battery, but the problem has not been solved. then I bought a $ 45 dc jack jack and plugged it in. Nothing has changed again. I said whether it is a charger and I paid a $ 55 and bought a charger. the problem still continues. my bios update version is A10. all my drivers are up to date. the battery is charging, but at a funny rate of 1% in 1 day. It works while connected to the charger but slow. There is no problem playing on the battery. very fast. I upgraded the existing 5448, considering whether to buy a new computer or improve my current one month before these problems. I am currently using 16 gb ram and 500 gb ssd. However, I cannot get SSD and RAM performance. It was the first time I regretted having bought dell. and I do not think I will choose again. Because of this problem, many people suffer and it is unbelievable that dell could not find a solution. I haven't tried searching through the forums, but there is still the same situation. When I plug in the charger, the white power light is on and off. The red light on the on-off button never lights up. How does the dell brand consider solving this problem? Also, when I was going to write a message to a man I was discussing, I saw that my private message was closed to send messages. Yes. what should I do.
I'm with you - if the drivers were totally bad, Dell would be getting MANY complaints and we would see more discussions here. My problem could just be a "one off" due to a faulty OS image load, or some other glitch. In fact, if I reloaded the Dell supplied driver package it would probably work fine. I didn't really test out the audio jacks fully until after I had installed quite a bit of software and then migrated the HDD to a new SSD. There are lots of places for a glitch to happen. But, I thought I would post my work-around in case anyone else had the same issue. I'll just let things stand for a while and see if RealTek, followed by Dell, will release updated HD Audio drivers to mitigate those security concerns.
