Hi mate, how did you achieve no windows sounds exactly? like set the system sound in the volume mixer to 0? I tried that way but it didn't solved my sound issue, I think maybe my understanding of turn off windows sounds is incorrect.

agree, I still can't believe I paid that much for this buggy machine...countless issues, includeing but not limited to hlg hdr video not displayed correctly (now solved) and this annoying sound issue.

In Windows, open the start menu.

Type, sounds

Select the change system sounds.

Change the sounds scheme to, no sounds.

Dell released today in their website the new Realtek audio driver (version 10.0.207)

Dell why it is too flat you use jbl and akg now , or you need to join samsung audio .

I did have the problem, seems for external sound outputs like usb links and Bluetooth the names change subtly, i.e. Ceol2 and Ceol3 created when you change the usb socket you use. Hope that helps somebody, helped me, eventually.
