Dell Latitude 5420 Audio Issues
Hey all,
Having issues with this particular model. We have just purchased nearly 200 of these to roll out and replace existing desktops to enable a more flexible way of working.
As all new machines we purchase we install a clean image of 21H1 on - install our apps via PDQ - Office 365, Mitel Micollab & Teams mainly.
What we are seeing with this particular model is the realtek audio driver is crashing randomly and breaking all audio on the machine (teams & micollab mainly) the only way to resolve is to restart. When this happens multiple times a day it can be extremely frustrating for a user.
We have tested numerous theories - testing 20H2 - testing out of the box image - testing with older audio drivers - testing with older .net - testing full updates via dell command & no updates via dell command - tested different BIOS configs and power saving settings - all with the same results.
We have raised a support case with Dell but this doesn't seem to be going anywhere - does anyone have any experience with this issue?
In event viewer it seems to be svchost that is crashing causing a 1002 error.
We have other Dell models - 7400/5410's setup exactly the same with zero issues so seems to be 5420 specific.
Any help or suggestions would be greatly appreciate before we return a lot of laptops and go back to HP.

I worked with Dell Support and the following steps have fixed this issue with the Dell Latitude 5420. I will post the steps for the solution below:
1. Press Windows+R. In the Run window type, 'appwiz.cpl'
2. Look for Realtek Audio and uninstall it.
3. Right-click on Start and select Device Manager
4. Expand System Devices here.
5. Right-click and Disable all entries that say Intel Smart Sound Technology.
6. Now, restart your machine and install the Realtek driver from here and then Waves Maxx application from here.

Have you tried downloading the Realtek audio drivers (and reinstalling them) directly from dell.com/support (Drivers and Downloads) using the service tag number(s) on your computer(s)? I've found that occasionally, Dell Command Update will not always update with the necessary driver(s) for my laptop (a 7490). Hope this information helps.
