macOS 10.14.6 macpro3,1 internal speaker disappears

After the second supplemental updates, I found out the internal speaker is missing.  That's it no longer shows on the Sound.  I don't know if it's just a coincident or not.

I tried to reset the whatever RAM by pressing the Alt Command P R keys when restarting, and you know how that is:  I can never be sure if I indeed hitting the keys at the right time given the fact that I am using the wireless Bluetooth keyboard and a non supported GPU.

Anyway, no luck with any of the resets I performed.  The machine connects with the Samsung Bluetooth speaker OK, just like before.  (One of the very odd things from day 1 is say I turned on the speaker and the machine connects for a second then it would immediately drops the connection and the video would get congested so much so Youtube thought there is a internet connection issue, well there is indeed a connection issue.  At that point I have to manually connect the BT speaker.  But this is just an aside.)

Hopefully money can work around this problem.  I ordered a CR2032 3V battery.  Maybe the existing one lost its power but even so I don't think it affects the presence or absence of the internal speaker.  But I just like to buy stuff.  Another prong of attack to this problem is I bought a USB mic and headphone jack adapter.  The latter solution hopefully can work around the problem.

UPDATE:
Apparently, or not so apparently, after the Supplemental updates, I need to manually do the patch updates because my whole macpro3,1 is a hack in order to upgrade to 10.14.6.  In the past, the dosdude patch would do a prompt automagically but not this time.  So after scratching my head for some hours I finally remember ahhh maybe I need to do that manually.  Unfortunately I placed the order to get some hardwares and hopefully the cancellation can go through.  After re-installing all the patches, the headphone port, internal speakers all work as they should be.  Magic.
