Audio was working with the ComboJack fix but I mistakenly updated through the appstore yesterday and caused a kernel panic. I reinstalled OS from recovery and re-implemented the ComboJack fix but now I'm not getting the pop-up like before. These are my system logs now regarding verbstub. Can't see verbstub in IORegistery anywhere.

Any help would be much appreciated.
