Update- Dell Tech advised to install driver followed by Dell Optimizer : issue resolved
After Realtek driver update to version 10.0.66.160, A04, I am having audio devices compatibility issues on Lattitude 7320 Detachable laptop running Windows 11: The Realtek driver description specifically states:"This audio driver requires the Waves MaxxAudio Pro or Dell Optimizer application to be installed to have full functionality." I appreciate my laptop may not be compatible with the Wave MaxxAudio Pro app, but it definitely came with Dell Optimizer app reinstalled. Yet, the Realtek driver seems to have removed the Audio controls functionality from Dell Optimizer?    
Waves MaxxAudio Pro vs Dell Optimiser vs Realtek audio driver
