My understanding is some of the problems are caused by the way the ASIO drivers were written.
I use a EMU 1820m. It has 2 mic inputs and 6 line inputs. And 8 ADAT inputs.
Each input is routed via the Patchmix interface. All strips are stereo. Input can be mono or stereo.
Patchmix sends each strip as stereo: sending to "ASIO In 31/32 Host"
Sonar preferences sees this input as "E-MU ASIO ASIO In 31"
The Track input dialog lists this input as:
Left E-MU ASIO ASIO In 31
Right E-MU ASIO ASIO In 31
Stereo E-MU ASIO ASIO In 31
Renaming them does not reduce the 3 options.
Given the number of items, I have been using stereo inputs strips in the patchmix to minimize the number of items listed.
So is this a SONAR issue or how the ASIO driver is written? Or both?
