Disable onboard audio in F2 Bios. Then do fresh start to remove realtek and any remaining OEM drivers. Admin Command Prompt systemreset -cleanpc It will leave an html file on the desktop telling you what was removed. Then reboot and install non dell drivers and apps Apps again.
Hello,  I use my XPS 8930 in a pro audio recording studio. Thanks to help in this community my pro audio PCIe card works great. BUT, I have to uninstall Realtek, Waves Maxx, and an audio driver attached to a monitor every time I turn on the pc. Help! How do I stop this?
XPS 8930, delete Realtek audio permanently
