Dell 5420 i7/i5 (Ice Lake) Audio & USB-Hub issues

Latitude 5420

Latitude 5420

A few minor things I've noticed and wanted to post incase anyone has similar issues.

 

I am on 21H1 and have recent updates:

1) latest audio driver (Realtek Semiconductor Corp., 6.0.9363.1, 2022-06-07) or a recent windows update is total junk

You MUST disable: "Enable Audio Enhancements" in order to use the soundcard.

This is true for both the onboard speakers as well as external USB soundcards. I find it ridiculous that I have to disable an 'enhancement' every time I go to use a new soundcard output. Thankfully it is a one time fix.

I have a fleet of these laptops and all of them recently had their audio stop working. I discovered this fix only after I had already ordered a new soundcard for one of them and tested it with the same issue. So I knew it was a driver issue not a hardware issue.

2) Dell DA310u has glaring issues.

  • My Logitech G502 when plugged into the hub will regularly stutter.
  • The laptop reports "Slow charger" I am using a standard 65w charger.

We are having issues with the 5x20 and 5x30's as well with the audio driver.

Do you install Dell Optimizer at all on these?  

 

Did you see there is a new audio driver for the 5x20? You can put it on the 5x30 as well, just not out yet for it https://www.dell.com/support/home/en-mk/drivers/driversdetails?driverid=pp6t5&oscode=wt64a&productcode=latitude-5420-laptop 

 

Have you tried to disable these yet? https://www.dell.com/community/Latitude/Fix-for-choppy-usb-headset-microphone-Disable-Intel-Smart-Sound/m-p/8249057#M44073

No Optimizer.

That driver must have been pushed to Command Update recently as checking updates was the first thing that I did.

Edit: Confirmed; new driver DOES NOT FIX the issue.

Enhancements and Intel Smart Sound Technology are not the same thing, I did not know of Intel SST until now.

I am installing the Realtek audio update as I write this. I will update once I check if it worked.

OK. I have one user I am trying the Optimizer on first. The driver was the one from around August.
