I have no control over what Cubase is showing as (only) options under Audio Connections (F4) > Output > Device Port
- Up until yesterday it was the speakers of my PC screen
- Yesterday it was the 3.5mm stereo jack at the back of my PC
- Today it is actually the speakers/headphones of my keyboard
So there’s always only one “choice” (which is really no choice at all), apparently at the fancy of Cubase.
I disable/enabled in the Windows Sound Control Panel any possible combinations of the above devices to try an influence the selection process (in Cubase itself there appears to be absolutely no way to do that), but Cubase is entirely oblivious to these actions, and just continues to make its pick of the day.
