I am getting random noises in sonar.  the sounds are as described.  I first thought I had clipped the kick drum.  I soloed it and
looped it to where I thought they were occuring.  but they occur at different spots.  I turned off all plug ins and still have them.  can not figure this one out
 

You may have to adjust the latency of you audio converter to a larger number.  If you're mixing, there's no reason not to set it at 1024 ms.

Ok thanks I will try that.  I am using a motu 1248 and I have it at 128  perhaps a bit too low.  I guess I thought my system could take it.  thanks again

Happens to me sometimes too. If want to keep the latency sometimes restarting Sonar or Windows helps.

Ok that seemed to do take care of it.  
 

I probably need to retweak my system.  thanks everyone!!
