Hi Drew,
my headphone jacks are fine after the update and I still get prompted if I plug them in.
check the log under C:\programdata\MSI\Dragon Center Updater\log.txt
look for the block of log entries that have a timesstamp of when you approx. installed the update.
does it say it successfully uninstalled and reinstalled Nahimic and the Realtek drivers?
Take a look at the device manager located in the control panel and see if you have any missing audio device drivers. if a driver is missing or is failing you'll see a exclamation mark or question mark next to it.
here's a copy of my log for reference:
