I am getting a "crackling" sound when using this program. My sound controler is {RealTek Audio HD(sst)}. Any ideas as to what the problem may be?

 I would think that you are exceeding the ability of your on-board sound chip to handle what is being needed to do the audio streaming of Music Creator.
 
I happen to use Sonar Platinum, but I believe what is going on with you is pretty straight forward.
 
If you are going to really utilize Music Creator to do any sort of complex songs, you are realistically going to want to buy yourself an actual dedicated audio interface, and I will explain.  Windows stores audio data in digital format, and yet when we hear it, we are hearing it because each audio clip has to get converted back to an analog sound (sound waves).  So, you on-board sound chip doesn't have to work very hard to deal with only a single left and right channel of playing back an MP3 or wave file or a WMA format music file, BUT - if you are using a program like Music Creator and working with plugin synths and effects, as well as multiple audio tracks, there is not really much of a chance that your on-board chip can do all of the conversions.  What happens is that during conversion, your CPU will get HAMMERED trying to do all of the conversion calculations and such.
 
THIS is why you want to get yourself an audio interface.  A dedicated audio interface will have dedicated purpose-built circuitry that will do all of those audio to digital conversions (and digital to audio), and this will free up your CPU to do other things.  This makes a HUGE difference in how much you can load up projects with Music Creator, or Sonar, or whatever recording software you use.  At some point, just relying on your CPU for going all of the work to deal with streaming audio, will result in crackles and pops and drop outs, and all of that.  
 
The OTHER thing an audio interface will give you, almost certainly, is a nice set of audio drivers called ASIO Drivers.  The ASIO spec is usually the Driver Mode you want to use, and your audio interface install/updates will put one on your system, tailored to work with the audio interface's hardware circuitry.
 
A reasonable dedicated audio interface will usually run about $150 or so, more if you buy one with more inputs and outputs, and also if the converters are super pro quality.  The $150 one will differ mainly from one costing $250-$300 will be how many ins/outs it comes with.  You will want at least 2 inputs with mic pre-amps and most interfaces have input jacks that handle quarter inch instrument cables or XLR inputs (mic).
 
Make SURE that whatever audio interface you are thinking of getting has audio drivers going up to Windows 10, so don't buy one that hasn't been updated past perhaps Windows 7, or at some point it will likely not work - once your Windows level goes past what Windows version they wrote audio interface drivers for.
 
I hope that helps - now, you COULD try seeing if you have a different Driver Mode you can specify - and perhaps one of them will work well enough for you to use, while you are evaluating audio interfaces for purchase.

WOW! Thank you very much Robert that was very helpful. I really appreciate the information, and advice.

My pleasure.  There are LOTS of helpful and friendly folks in these forums, and while you certainly have a bunch of stuff to wade into and through, learning the software and finding your footing, folks in the forums will really work hard to help you, as issues arise for you.
 
These forums are one of the strengths of Sonar, and lots of folks give back because they have been helped when THEY were trying to figure it all out.  That would most definitely apply to me.  I am STILL learning every day I visit these forums.

I don't know a whole lot about computers, enough to be dangerous, if you will. The information you gave me was clear and made sense. I have my eye on an audio interface ( a Steinberg UR22) and hope to be picking it up today. Thanks again for the info, much appreciated.

Welcome, gentlemen. Faced with such a problem: 64 sound crackles and freezes in 7. Long sinned on zvukavuhu Xtreme Music X-Fi Creative, I tried many drayverov- avail. Bios obnovlyal.Stal use integrated zvukavuhoy (before that was turned off in the BIOS) Howbeit the problem began to wear less pronounced, but still ischezla.Tresk pair is heard. On zabugornyh suportah found a similar theme in her boyfriend proposed as a solution to limit the number of operatives is less than 4 it solved the problem, the sound became perfect. As there by the sound of other problems. I would like to, with your help, ladies and gentlemen, to find out what is the actual catch. As can be connected number of operatives and sound? Mother: asus m2n e-sl. \ 4x1 800mhz ddr2. At 32 hr there is no problem.

I am not sure what to do with the above post from the new forum member, 'FatalllNoA'.
 
The post is pretty much unreadable, and at first (and second) glances seems like auto-generated robot nonsense, BUT I looked up some of the words, and they are actually Russian, so maybe it's OK but I just cannot read it to make heads or tails out of it - and perhaps with English not being a strong language for the individual, maybe that explains it.
 
I'll do the wait and see for a bit here.

It's spam - I just flagged a couple of his other posts in F&R

Just wanted to let you all know that the problem seems to be fixed. Got the audio interface and no more sound cracking. Thanks again for all the info and support much appreciated.
