Hi. All of a sudden, any new project I create, or any old project I open, which were most definitely all in 24-bit, are 16-bit. I have a Focusrite pro24dsp with latest driver and firmware. In my Sonar Driver Settings, audio driver bit depth is greyed out at 24-bit, like it usually is. The issue does not happen in X2a. Heeelp! I'm totally out of ideas on this one.

Looking in the wrong place. These are the driver settings. The record bit depth is set in Preferences > File > Audio Data. FWIW, it has been this way for some time. X2 is the same.

Ahh, I see, thanks. Quite odd, I don't recall ever having to manually set this, nor do I get why it set itself to 16-bit. Good to know.
