I recently got 2 audiofire 12s and cannot get them to work in Sonar.  I've successfully managed to confuse myself.  Windows 7 recognizes them and Sonar recognizes that they're there, but will not list them under the Driver tab. 
 
"There are no audio devices for the current driver model on your system.  Please go to Options/Audio and choose a different driver model."
 
I've tried going through ASIO, WDM/KS, and MME, but still no luck.  Any suggestions?

Windows 7 recognizes them and Sonar recognizes that they're there, but will not list them under the Driver tab. 

Then what makes you think Sonar recognized it? 


ASIO mode only allows one soundcard at a time. Try WDM mode.
