Hmmm....
I'm using Sonar X1, if i start scope project from scratch, i cannot use 16bit resolution in Sonar at all. Sonar lists audio driver bit depth at 24bit without possibility to change that to any other value. It means Sonar see asio driver as 32bit integer...
At the same time if i use XTC mode in Sonar and start xtc asio control panel, and chose 16bit mode, Sonar still see Scope Pci ASIO as 24-bit!
The only solution for 16bit asio in Sonar is to start old Scope project that used 16bit driver. It means that in Scope 5.1 16bit ASIO drivers are still there, but they are for some reason not listed under Sofftware IO options. They are anyway listed and required in older project files.
