Anyway I'm pretty sure they are, other USB devices always work. 

there is 2 settings in the asio driver, for the in / outs for the unit.. you have set them the same , so the front of the unit matches the driver ?

I use the same unit, so find it odd your having issue with it.. in your audio in / out prefs your sure other stuff is OFF.. and stuff like emu patchmix etc?

you might find it's some legacy asio driver.. thats not the correct driver.. it should be displaying saffire etc.. not in front of mine to check

In audio|devices:

Input drivers ; 
Focusrite USB ASIO Driver Input 1
Output drivers ;
Focusrite USB ASIO Driver Output 1
Focusrite USB ASIO Driver Output 3

These are the only drivers (They are all checked)

In audio|driver settings:
Playback timing master and recording timing master are both set to driver 1
(of course record is input and playback is output)

I'm not sure if this is all correct or not..

What version of Windows are you running? 32 or 64 bit? What version of Sonar X1 are you running? 32 or 64 bit?

Did you check the Windows Device Manager to see if the Saffire is listed under sound devices?  

Did you try switching to WDM mode? 

Sonar and Windows 7 are both 64 bit, and yes in device manager it says it is working properly.

Try WDM mode.

Did you download the latest drivers for the Saffire from the Focusrite site? 

You don't happen to have some other audio making application like Windows Media Player or iTunes already open do you?

Also, the manual says to make sure you run the installer before you plug in the Saffire. Did you do that? If not, uninstall the driver, unplug the Saffire, reboot, run the installer and then plug in the Saffire. This is very important. 

Nope, WDM doesn't work either. 
I have downloaded the latest drivers, and no, I do not have anything open when I am using Sonar.


EDIT: 
@daveny5 
I think I did plug the Saffire in first... I didnt get a manual as it was secondhand. I will try it now

You're not using a USB microphone, are you?
