@hawkeys46,
I managed to fix the problem with the missing Volume bar. What it didn't like was the Realtek HD Audio Manager. I had to uninstall it before doing the upgrade to 22000.51, also I then installed a Realtek driver that was not combined with the HD Audio Manager.
Removing the Audio Manager after the update to 22000.51 did not eliminate the problem, had to go back restoring the system to a previous older build remove the Audio manager, install a different version of the Realtek HD audio driver and then finally do the upgrade again to 22000.51.
Finally it came up correctly as you can see on the shots below 😉
What a pain though !
