Sonar X1 & Sonar X2 loud plop and then audio stops

Hi there,

A huge problem has started today that is destroying an important recording session...I had Sonar X1 and a Roland Edirol UA-25EX that worked fine yesterday.  Today all of a sudden during recording and playback of a multiple track project all of a sudden a loud click/plop was heard and the audio stopped.

After restarting Sonar everything works again but the problem occurs very often. To solve it I went through quite a lot of effort:


-At first I tried re-installing the audio drivers of the Edirol, but they didn't run through the installation process, after detection the installation and installation of the drivers, the install program didn't pick up with a  'NEXT' as expected but keeps waiting , the option 'next' just remained greyed out In fact it said the driver installation didn't complete, making me suspect the audio device was broken. (I tried de-installing first too)
There was audio in windows though, in Sonar the audio device was not present.

- I bought a new audio device, a Roland QUAD CAPTURE, installed it, the installation now was 100% as expected, Sonar worked but then the problem started again.

- I installed Sonar X2, hoping the software installation was the problem, but still, popping/clicking at random moments as if something interrupts the driver or something! 

-BTW I Disabled virus scanner etc. 

What I noticed now is that at the moment the pop occurs, volume levels on the output are 100% , when I stop and start the audio engine, the levels go to 100%!

Anybody have an idea of what is going on??? 

BTW: I installed Spotify today, although I can't see any connection with that...


regards,

Marcel

Welcome to the forum Marcel
 
Just for giggles, try using the Concrete Limiter (if you have it) or the Boost 11 limiter on all of your busses.  If it is a psychotic sound pulse from a bad synth patch or extreme summing, this will let you play through the tracks to determine which one is overloading your audio driver.

Thanks Glen, 

I have replaced the only plugin I don't use very often (A Trillian Bass) because the problem started when I played with that track today, and up until now I didn't have any crashes! So maybe that is the unstable factor here...lets hope its solved now!
