My sonar2 essential is suddenly not recognizing my saffire pro 24 dsp. It was all working great for several weeks since initial installation- then I fired up Sonar2 today and it was only recognizing the integrated realtek device. Here is what I see: 1) In Sonar2 audio preferences - the saffire channels are all greyed out - and cannot be selected. The Realtek is selected. 2) In win7 control panel - the saffire is selected as default audio for recording and playback 3) Under saffire mix control - it recognizes sound (and I hear all inputs) - and indicates everything is good. 4) In sonar 2 midi preferences ... it recognizes the saffire midi! Any suggestions? IW

Have you tried rebooting?  That sort of thing has happened tome before, and rebooting fixed it forme.

Just a thought,

  Yes - I tried rebooting. It didn't help.

If you're in ASIO mode try clicking the pulldown (in Sonar audio preferences) that shows the Realtek & selecting the Saffire. ASIO lets you have only 1 interface selected at a time.

edit to add: or try deselecting the Realtek ports & then selecting the Saffire ones.

Did you try the new upgrade for saffire pro24dsp?

+1 on Ducatibruce2's suggestion.  Deselect the Realtek interface, and it might open up the Saffire for you.

Try using System Restore to take it back a day or two.  I find best results when using it in safe mode (Press F8 during bootup).

  OK - I'm really struggling after playing with this for 2 hours - and no success. Here is what I tried: 1) I tried the pull down in the driver setting and no luck - only the realtek or none. So I tried "none" and apply - but it kept reverting back to the realtek. 2) So - I did a system restore to about 10 days ago. Well - that was before I installed sonar2 essential. So - I reinstalled sonar2 essential. 3) Well - I'm not sure I'm any better off. According to focusrite - I should be able to select ASIO Saffire (8in 4 out) in the record latency pull down. Well - it is there from the pulldown... but it ALWAYS reverts back to generic low latency asio driver speakers (saffire audio1). So - now under audio input drivers I have a generic low latency ASIO driver microphone saffire. After that I have all the saffire pro input drivers all greyed out that I used to have and expect. Under output drivers I have similar nonsense (the single generic driver ...and then the greyed out saffire outputs. Basically - Sonar now treats my focusrite saffire pro 24 dsp as a single input and single output with no other option for input/output flexibility. Yes - I have the latest drivers and saffire mix control 3.0 This is pretty discouraging. To be honest - I'm not sure how to uninstall and re-install all the saffire drivers to try and start from scratch. From the control panel it says I have the 3/36/2012 4.0.0.13485 driver version etc. IW

I also use the Saffire pro24dsp... still on old drivers... and no trouble here... will keep my fingers crossed.
Have you tried going back to X1 or 8.5?  Seems this would tell you if it's the saffire or an X2 issue.... 

 This is new computer, fresh system, worked great for 10 days - now unusable
