XPS 15 9520 - Windows notification sounds are delayed

Question

Whenever Windows 11 plays a notification sound, it's delayed by a couple hundred milliseconds up to 1 second. This is very annoying and makes the whole system feel buggy and slow.

My drivers are all up to date. What else can I do?

Alright, finally I found some time to work on this issue. I tried many things, like reinstalling drivers, updating everything with no avail.

In the end I played around in the device manager and it turned out that when I uninstall the device, scan for new hardware (which installs it again) the issue is gone. However this only lasts until the next reboot where the issue is back again.

Since I could reproduce the approach above quite well I decided to create a script which does that automatically on startup.

Open command line
use: "pnputil /enum-devices /class MEDIA" and look for the device ID of "Realtek Audio"
Create a batch file as below, and update the id
Go to task scheduler, and create a task which runs the batch file on startup
This will uninstall the device forcefully, and start a scan which reinstalls it on startup

REM Uninstall device and initiate a scan for devices which "reinstalls" it
pnputil /force /remove-device "INTELAUDIO\FUNC_01&VEN_10EC&DEV_0289&SUBSYS_10280B19&REV_1000\5&2a97a754&0&0001"
pnputil /scan-devices

I hope this helps some people to circumnavigate the issue until there's a proper fix. See also my topic on the Windows help forum for additional details

This Windows Report page has some suggestions though most of them deal with lag longer than the 1 second that you are hearing.

I doubt that any of these tips can help to fix the issue. I just had a dell technitian verify all the drivers on my machine. The only thing they had left was to reinstall windows. Since the issue exists since I installed windows, I doubt that's going to help

The last suggestion I heared was to reinstall windows entirely to get that supid McAffee antivirus again. I also don't have the time to reinstall all software and make backups at the moment
