Cubase 12 - Audio Card Buffer Size Change No Longer Changes Within Cubase - No Sound

I am using Cubase 12 on Windows 10 with an RME Babyface soundcard. In previous versions of Cubase, any change to latency I applied using RME’s soundcard settings window were immediately reflected within Cubase’s Sound Card settings and the audio set perfectly. Now within Cubase 12 I am experiencing the following issue:

1 - I change buffer size from 64 samples to 2048 on the Soundcard (due to playback crackling, etc.)
2 - In Cubase I STILL see the prior lower latency setting (for 64 samples) displayed
3 - When I go into Cubase and select the control panel for the RME and change these buffer settings from there, I no longer get sound., even after hitting Reset
4 - I tried this and changed back and forth a few times without success (restarted Cubase 12 too and it was still silent).
5 - I also set it to No Driver and then reset to the Fireface USB driver (RME) and Cubase 12 still would not accept the change and produce sound.

Again, this worked smoothly in Cubase 11. . . it appears it may not have been tested before the release of the new version ( I have been using Cubase since the 90’s).

I hope Steinberg can add this to your review/updates.

Thanks!
