Console pointed me to:
PlugIn Identifier: com.rogueamoeba.InstantOn.driver
PlugIn Version: 8.4.3 (8.4.3)
This was keeping CoreAudio from launching, thus no Sound preference pane, slow performance in browsing and strange non-responsiveness in Terminal. Once I removed the InstantOn driver from rogueamoeba (part of Airfoil). Everything works fine now.
Of course, I found this after Dimitry posted the right answer. Next time I'll check my posts before chasing the beast.
I do not have those files to remove and this is getting very frustrating, i was told to update my OS so that my internal camera would work now both the camera and the sound aren't working.
Has anyone found a fix for the slow web browsing? Currently having this issue with High Sierra 10.13.2
