Hey Sonar Geniuses,
 
I need help.  I just purchased a Focusrite Scarlett 18i20 and the preamps sound awesome and the playback even sounded better than my previous interface (Roland Quad Capture) until this problem arose. I never had any problems with the quad capture, however after trying to get the scarlett all set up I'm having major issues.  I contacted Focusrite earlier today and am waiting for a reply but I thought it wouldn't hurt to see if any of you Sonar Geniuses had any advice.
 
I'm running Sonar Producer X3e on a 64-bit Windows 7 computer with 8 GB of ram and a 2.7 gHz AMD Phenom II 6-core processor. Recording at 24-bit, 96k sample rate. ASIO driver.
 
The Focusrite Scarlet 18i20 makes a pop noise and all audio output drops out.  The unit and computer both see it as still connected and the included MixControl software and the LED indicators on the unit show input signals, but no audio will go through the output.  Occasionally there are other pop noises during playback as well but once it stops playback I have to re-start sonar and reboot the Scarlett.  This happens many times within an hour and is becoming a real problem. I have tried adjusting the buffer size but have had the same problems on all settings, even maxed out.  I have never had any problems with my old quad capture and I was also recording at 24-bit, 96k.  I really like the Focusrite Scarlett so I hope this is just a minor problem that can be fixed.
 
Any help would be greatly appreciated.
 
Thanks,
AR
 

I would hold out for Focusrite support.  I've used them several times in the past and they have went "overboard" helping me.  I used to have a Saffire Pro 40.
