Mediabay Routing Problem Cubase 11

Tried any kind of solutions, restarted cubase, saved empty project templates, restarted after any little changes… nothing.
By the way, I can work with this solutions now, It just annoys me to have to remember to put the mediabay outputs on cue in Cubase every time I start work.

it bothers me a lot but really I can’t find the original source of this problem.

A question (and thx for your support and your time!) do u use a raydat?

No. I only use the Universal Audio Apollo USB on this system for now.
Used an RME Fireface 800 on my old system, an UR22 on the office workstation and a Native Instruments Komplete Audio 6 on the laptop.
The new system is prepared to use the RME in the future, but not configured to do so now.

today I make some tests…
complete reset of total mix, complete reset of outputs in cubase.
Starting from zero point.

Nothing to do.
In my opinion Mediabay internal audio routing is a little tricky or strange. Seems audio from mediabay was developed to point on system (win 10) main audio outoputs, normally 1/2 of any audio interface. If you change this conditions MEDIABAY internal routing was a little buggy.

Hope someone in Steinberg can analyze this.

No. System audio plays no rule inside Cubase.

yes I know… But mediabay internal audio seems to be different.

absolutely only hypothesis

SOLVED! Thx to Steinberg!
very very simple…
Cubase 11 preferences was damaged.
once reinitialize mediabay it works as it should!
