  1. Hi Andre, I haven't posted a trace yet becuase the original instructions told us to run the trace until we expereianced a problem and I have yet to expereiance one while running the trace. But not being sure if that was still a condition I realized i should let you know whats going on and see if that changed the strategy at this point. I did run one trace where I had sonar working plus allot of other activity and the sumary information then listed many processes, with USB at the top, but again, not sure if these are right conditions under which i should generate the trace file. The Latency monitor app still reports I have issues that could cause audio drop outs,its just I have yet to expereiance them//Also FYI, I will be traveling later this week away from my home studio compouter so should I delay to respond, you know why. Again, thans for your time and help. I sincerely appreciate it HSC III
  2. Fuirst thank you so much for helping me. I made all the update as you suggested. I haven't had a chance to push the compute using Sonar Xl1, however, I have yet to expereiance any drops when just playing audio,wheter its itunes of a different file format in a different player. Prior to the updates the drop outs where coming fairly often as of the last 2 weeks. However after running for 4-5 minutes the Latency monitor applciation states i have issues will likely cause drop outs,clicks etc. ( see below) I have stopped using my powered USB port excpr when its explcitily needed but it looks like USB is still a source of issues. In device manager there looked to be way too many instances of generic USB Root Hub, but I'm not sure what action to take I'll run the test to create another trace file so should you request it,I'll it hready to send thanks again CONCLUSION _________________________________________________________________________________________________________ Your system appears to be having trouble handling real-time audio and other tasks.

  3. Thank you very much I just PM's you the link to the trace file
  4. I'm using Sonar XL1 Producer with win 7 home premium ( 64) and the audio drop outs are killing me so its time to solve the issue! I followed the instructions to install the SDK Performance tool, which I ran using the cmd with the switches indicated in the tutorial. As soon as I has a major audio drop out, I ended the trace ,creating the .etl file. I continued to follow the instructions and I think I got to the correct place to identify the problem, but I’m not sure exactly what to do I have attached screen shots of the graph, the section I selected and the summary table. If someone can look at them and tell me what they see or if I have to do something else I would be sincerely appreciative I'm sure about the add image to post feature because I don't thing the info is readbale so I hope the files are still available to be downloaded Thank you very much HSC III
