Oh and disable Intel speedstep in BIOS (Speedstep is evil!)... ta

Yes, it is very evil indeed! I learned to disable that garbage long ago, even on another slightly-older mobo. So at this time, Speedstep is/was disabled. C1E also disabled.
 
UPDATE: I put the Nvidia GTX670 back into the machine and uninstalled the drivers. I then tested Sonar to get the glitches and pops, and it did not occur. LatencyMon.exe reported all very good latencies. None were over 1ms. So this confirms an incompatibility with Nvidia drivers somehow, someway. Either Sonar is at fault or Nvidia is at fault.
 
At this time, I am attempting to roll back to an older driver set. However, it is very difficult and wasting a lot of my time.

Drivers it will be sadly, Sonar is on a whole different application layer.

You are defnately doing a nvidia custom install with the bare minimum required? Just the driver itself that's it? Anyway good luck...

Trying to, but that's the hard part. Even though I disabled the "automatic driver install" setting in Windows, it still seems to do it. Windows will install just the basic driver, and not all the happy Nvidia stuff, which by the way, isn't all that bad. But either way, even the basic driver install causes the card to glitch the audio.
 
So is it REALLY just the drivers, or is it how Sonar communicates to the drivers for 2D graphics rendering? I'll have to try to get other applications to glitch an audio stream.
 
I've submitted a feedback form to Nvidia, but I don't expect much from that.
 
And...why couldn't it be Sonar causing the incompatibilies with Nvidia drivers?  After all, the glitching is at its worst when the window is maximized. Or maybe that's a Windows thing, not a top-layer software thing, as Alex has mentioned.

Watching how this turns out.

May I ask if you let windows load the default drive for your video card and just see if that helps? Not the nvidia driver.

Thanks for tuning in. The default windows driver does the same thing; no improvements.
 
EDIT (2013.11.3): Wait...you mean the default of the default, basic 640x480 driver?  If so, then YES, it does help. No issues! However, 1993 called, and it wants its screen resolution back!

 
More food for thought: I downloaded and installed Cubase Elements. I inserted an Instrument Track of Dimension Pro for test. Upon rapidly moving its MIDI notes around in Cubase's PRV, only slight crackles, pops and scratchiness were heard--overall very minimal. LatencyMon.exe running in the background during the Cubase experiments revealed nowhere near the amount of latency created by Sonar and the Nvidia drivers. Worse offenders in the list were dxgkrnl.sys and nvlddmlm.sys at 1.06ms and 0.735ms, respectively...about 3-4x less than the Sonar tests.
 
Now here's the crappy truth: If Sonar is partly the cause of the pops and clicks due to the way graphics are executed, then am I left in the shadows since I am still on X2a? Cakewalk/Gibson won't do a hotfix or an update for us "old timers," even though I upgraded to X2a just this year. Do I really need to upgrade to X3c for a potential fix...maybe? Outlook not so good seeing that others, even on X3, complain of similar issues.

Hi, Buying in (from another similar thread) this actually improves (? too scared to say solved) my problem.

SEE EDIT TWO POSTS UP.
 
Hi Jinxy. Yeah, I saw your thread, and I asked what graphics card you have.  Looks like another Nvidia victim! And you have a very similar CPU. Perhaps the combination of them both (and perhaps the motherboards running the older Core2Duos are to blame)?  As for the default driver, I will try it again and report back.  As of now, I have rolled-back to the very first edition of drivers that support the GTX 670; they are not any better than the most recent, up-to-date set of drivers.
 
Speaking of rollbacks, maybe I'll install X1 Producer to see if it existed back then. Overall, this is very frustrating! I should be making music and not worrying about Snap, Crackle and Pop!
 

Hey2:43  WE NEED A SUPPORT GROUP!!!!!!!!
 
Here's my kicka....un-installeed NVidia......marginal difference...re-installed & it is a problem.
 
When I'm playing a project & spin the mouse around.. THE NOWTIME MARKER STALLS...while still playing...& skips...GO FIGURE?
 
LOOKS LIKE A NEW SOUNDCARD? Anyone got any ideas...pllllllleeeeeeeeeeeeeeeeeeze

Maybe this will trigger something....
