OK, I have a new project that I have barely worked on which seems to have a major problem already:
 
I can no longer work on the project for more than a minute or two before I hear a loud static-pop through my speakers and then major digital noise starts feeding through my speakers at which point I have to quickly exit Sonar.  It is kind of like major digital clipping that seems to happen for no reason.  When this happens I have noticed that the VU meter for Session Drummer spikes to 99 db and shows completely red which does not clear until I close the program.
 
I have seen this before in Sonar X2, but it was rare and I'm not sure if it is related to Session Drummer or not.
 
Has anyone else had this problem?  Does anyone know what could be the problem?
 
I think I may have to scrap this project, start another and hope this doesn't keep happening.
 
 

I've never experienced anything like that, but my first thought was something about routing/possible feedback loop.

Something similar happens to me when I time stretch a few audio clips.
 

without going too deep, as I used to have this problem(post back for specifics)...
Something in your audio driver doesn't play well with sonar at all times.
you won't like this but it's corrupted.
 
completely remove the offending driver(including in the registry).
then restart sonar so you get the no driver/asio message.
then reinstall your audio driver.
 
worked for me, hope this helps

sheesh I' been off for a while
I'm on X3D, cust. since 3.11

Ahh, I think there are a couple of things for me to try:  I was playing with stretching audio in this project and I will try reinstalling my drivers.
 
 

I had probelms like this when I used a motu ultralite and could never find out what the problem was then I switched to an RME Fireface 400 and all the problems went away.

I am wondering if it does have something to do with my MOTU, but I will try reinstalling the drivers, hopefully it isn't related to the stretching of clips, because that is handy.

If your MOTU is a Hybrid, hook it up via USB and see if it happens.
