Getting the standard ‘oops there’s an issue with your playback device’.  
I do NOT have fx listed anywhere in my device settings or audio settings, but I did have it previously when I was running Win 11.  
Any advice?

In Device Manager, please check if FxSound Enhancer shows any error. FxSound Enhancer will be under Sound, video and game controllers. Uninstall FxSound with delete driver option checked,

In device manager, fx doesn’t show at all.

That command did succeed but still get the same error (oops).

Even after the install it doesn’t show
