  1. Solution 4 worked for me. I had a “Realtek 8723DE Wireless LAN 802.11n PCI-E NIC” enabled (but I’m running wired so it was not needed). I disabled in Network Settings and my Windows 11 stuttering is gone!! To note, this was a Dell Vostro 5880 purchased Nov 2020 which had Win10, which I upgraded to Win11, which is when my audio stuttering became apparent.

    Thank you!
