Hey all,
 
About 1 in 5 times, when I open any project, the audio tracks have a LOT of noise in them.  The work around is to turn the audio engine off and on a few times with the switch in the transport module, and presto, crystal clear again.  Any ideas?  I would like to perform these songs and use Sonar to play the accompaniment, but I can't rely on the audio engine to be clear with out testing it.
 
Aslo, I want to buy about 30 songs and what online outlet do you like best?
 
Your the best, Ron
 
 
 

The audio engine isnt producing the noise. The noise is being produced by something in your project, like a plugin effect.
So the million $$$ question is, what effect do you have? Better yet, disable one at a time until it stops behaving like that..

Does this happen after a reboot more often than simply opening another project in the same session? If so, I would make sure that you either:
 
1) Wait until your computer's auto-updaters have run before starting a session, or
 
2) Disable all auto-updaters, including AV and Windows Updates. You can always update manually when you aren't recording.

OK, I'll try to isolate it.

Good point, I don't wait until the computor has run it's updates, and that seems more like the problem since the audio is fine with plugs running, so why the problem sometimes.  I also like to open 9 projects and shrink them into a list and highlight the first one to play along with it.  The thought is that  I will perform out with all the great effect in place.  But, I can be practicing for 45 minutes and have this happen again.
 

I just opened 9 projects as usual, selected them one at atime with no problem the first time through, and then about half way through the list the second time, noise again.  I turned of and on each plug one at time, still has the noise, no updates at the moment.

Okay, I have a send on the master bus that goes to a bus I use for headsets and the head set bus goes to maudio sound card analog out 3/4.  When I turned off the send to the head set bus it clears up the noise.  Thinking I could eliminate the head set bus on each project I went to the project and in came the noise even with head set bus deleted and head sets going directly to maudio output 3/4, output heads ate plugged into.  
 
By the way if I turn the echo off the mic channel or the guitar channel the noise goes away.  I just can't figure out why it is only an intermittent anomaly.  More times than not the set up I am using works fine!
 
The problem does seem to centered around the live mic channel or live guitar channel.  I have turned off all sends and plugs with and the problem is still there, with the exception of when I turned off the send from the master bus to the head set bus, and that cleared up noise.
 
As I mentioned before, turning off the audio engine clears the problem anytime and I can play the project over and over while it is still open with no problem at all, no matter how long I practice on that project, hours at a time and no problem.

Well, if you are still using your MAudio Delta, then it isn't the usual suspects related to USB conflicts, but it might still be something running on a shared interrupt in your PCI bus. Has this only recently started happening?
 
See if you can determine what devices are sharing interrupts. You may be able to swap PCI slots to resolve the issue. If you still have the motherboard specification sheet, you'll be able to see which slot uses which interrupt. Something is coming "on" that is causing your interface to make noise.
 
I should have asked earlier, but how many audio tracks are in your project and are there more tracks playing at once when you start hearing the noise? If you have a large project, you may be running into disk throughput issues. This will also cause crackling noises or dropouts.

Dan
 

Thanks for the replies! 
     The projects have 15 to 25 tracks, with a sure mic connected directly to the LCR input jack on the MAudio 1010LT and the Ibenez acoustic with an add on hole pick up, (LR Biagio) I think it says on it, also connected directly to the 1010LT via an input jack to 1010LT.  A typical project may have 4 instances of Cakewalk TTS-1.  I only use the first 4 timbral channels on each TTS-1, set the TTS-1 so that Timbral 1 goes to output 1, and set an audio track so that it picks it up in midi channel 1.  TTS-1 timbral 2 is set to output 2 and is picked up in another separate audio track on midi channel 2 and so forth.  I then end up with say 12 separate midi tracks, each with a separate audio tracks and a two live audio tracks for the mic which both use the same input from 1010LT LCR jack, and another audio track for the guitar pick up through 1010LT on a separate input.
     I may run the kick on one track, the snare on another track, hi hat on another, and send the drums to the same bus. The bus goes to the master bus and the master to 1010LT analog output 1/2.  Then instruments such as piano, banjo, etc. ore set the same way and sent to one bus called instruments, to master and out.
I use sonitus equalizer plug in a few tracks and Breverb in one bus with sends from a couple of tracks to it.    
     Now there are two variables.  I did not have this problem before the upgrade to Sonar X2, and, I am not sure when I got the pick up for the guitar, but it may have been around the same time as the upgrade to X2.
     I open each of the nine projects at the same time, shrink them down and highlight the first one, play along with it, then the second, play along with it, and so on.  Then highlight one and the noise is not present at first and begins when I play the project.  I can turn off and on the audio engine and the noise goes away, or, I can turn off the input echo on the live mic audio track or guitar live pick up track and the noise goes away.
     This can happen on any of the projects, and all of the projects work fine but this noise appears at will it seems, tonight about once in 10 projects openings.  Turning off the plugs or sends does not stop the noise.
     Tonight the computor ran for a couple of hours before I tried this again, so intial set up processes are not the culprit. 
 
 
 
 
 
 

I would like to step back and start with some more basic stuff.
 
Can you please provide the following information?
 
1. Audio interface: Sample Rate and ASIO Buffer Size
 
2. Sonar: Driver Mode, Sample Rate, Record Bit-Depth, Total Roundtrip Latency
 
3. Do you have this problem with a new project and only perhaps a single imported audio track of an MP3 or WMV song file?
 
4.  For one of these problem projects, what happens if you hit 'E' on your computer keyboard, which will Bypass All Effects?  (afterwards, you can hit 'E' again and they will all turn back on).
 
5.  Does your computer have a Wi-Fi adapter?  If so, what happens if you temporarily disable or turn off the Wi-Fi adapter, and then open Sonar and open a problem project?
 
6.  What happens if you temporarily suspend your antivirus software, and then open Sonar and open a problem project?
 
Please review and respond to each of the above, and try to do each of the above tests one at a time, rather than all at once, so we can determine the effect (or lack of effect), of each of the tests.
 
Thanks,
