I am using a UFX and my drivers are defined as expected...You are doing something wrong...

I've reviewed lots of RME interfaces over the years with Sonar, and never had a problem (except affording the high-end ones )
 
Have you ever had Cubase installed on your system? If so I may have an explanation for what you're seeing.

Grass not greener here. . .

 
You have to hook up the watering system correctly. 

If you have Samplitude installed, it installs a Generic ASIO driver.
Set Sonar to use ASIO driver mode... and select the RME ASIO driver.
That's all there is to it...

I am a staunch RME supporter and have owned and used many of their products over the years. I have three different live mixing systems (Software Audio Console) that use RME Raydat cards. I have a Fireface UFX and it is rock solid, behaves as expected, etc. That said, I have an RME Digiface with a PCi-ExpressCard that does not work at all in my new notebook computer running Windows 8.1. I even reverted to Windows 7 to test - no go. RME blames it on the computer manufacturer and the computer manufacturer blames it on RME. This all works fine on my older notebook computer, so who knows what the real problem is. I have been working on this one for months with no satisfaction. My satisfaction has to come from the other systems that work flawlessly. They all run Windows 8.1 now, as well, and have the latest RME drivers.

I had the Cubase demo installed.  And the Studio One 2.6.   And Ableton.  Now Sonar x3.  Trying everything out there.
 
The fact that the software is using a driver I have deselected indicates a software bug or glitch, or at the very least poorly documented feature.
 
RME has been rock solid and works perfectly with every other app, multiple apps open at once, it is updated to latest drivers and firmware, that its a reasonable to assume a software issue.
 
This is like a test drive where a part of the car falls off.  Most of them may be good cars, but the one I drove had/has issues.

I have done this.  The Generic driver is greyed and cannot be selected, the RME devices are chosen for input and output.
 
Sorry for my poor attitude, but time is money and I cant get bogged with a buggy application or a protracted conversation.

NO such driver appears in Smplitude.  ASIO4All not installed.

Using USB drivers, as low as 48 samples, 4.3ms reported round trip.  BUT still get a 3-4s pause after clsing prefs every time while Generic lld does something.

Or apparently, the time required to find out the source of the problem and fix it. And that's fine; you can make music with any DAW. I use Sonar because time is money for me as well, and of the DAWs I own (which is basically all of them), for my needs Sonar gets projects done faster, whether it's narration, a remix, or straight ahead recording. But you certainly don't NEED to use Sonar. 
 
However I'd still recommend trying to find the source of the problem. It's possible that there is some incompatibility with Sonar that relates uniquely to your system and how it's configured, but it's also possible that whatever Sonar is flagging could influence other programs as well. 
 
As to your attitude, you're not thinking logically. There are many people on this forum who use RME interfaces. If there was a problem with Sonar and it was a "buggy application," your problem would have shown up before or you at least wouldn't be getting a bunch of RME users saying they don't have problems. FWIW I've never been able to get the Generic ASIO driver that Cubase installed off my system, and believe me, I've tried because it wants to take over if I boot any program without remembering to turn on an audio interface first. I'm sure Steinberg's motivations were good - "We will make sure you can run using ASIO even with a laptop" or whatever - but not everyone uses Cubase.
 
I would never install multiple trial versions all at once. I would set a system restore point, evaluate a program for a week, restore, then evaluate the next program.

Well if you're running at 48 samples, I'll start using the generic ASIO driver instead 
 
Maybe Sonar is using the real driver, but it keeps getting queried.
