Okay, I've been getting a 500 error from the forum server every time I try to post another message on the original thread -- Here: http://forum.cakewalk.com...793650&mpage=1#2798882 -- and btw, the Cakewalk Technical Support email server reported that it was not working -- so here's a new thread with the update: UPDATE: OK, went into Ctl Panel, there were two audio devices already disabled, one for the NVidia card and one by Realtek (on the motherboard).

Looked for conflicts, found one IRQ conflict that had both Universal Audio Device and 'High Definition Audio' both on IRQ 17.

Went into the BIOS and disabled the Realtek there--now it doesn't appear in the Device Manager anymore. NVidia is still present in Device Manager but is disabled.

btw, already checked defrag, 0%. Also went through the Avid list, all taken care of already.

Crashed three times last night, including a first-playthrough-after cold boot, just 30 seconds in. The previous night I worked for a good two hours straight, THEN crashed.

I've been doing a cold restart after every crash, trying to keep from introducing more errors because of not letting Windows clean house.

I haven't touched IRQs in ages. Not necessary. Let Windows handle it. What version of Windows? 32 or 64 bit? 

I wouldn't disable the Realtek in the BIOS. That could cause problems. You can disable it in Device Manager, but that's not necessary either. Just setup Sonar to use only your other soundcard. What soundcard do you have?

With all that crashing, you should run a disk scan. 

You could also run Memtest to rule out a RAM problem.

What version of Windows? (7/8/etc)

32/64 Windows?

Is Windows up to current maintenance levels?

What audio interface do you have?

For your audio interface, what exact driver version are you using?

If your audio interface connects through USB, are you plugged into USB 2 or 3 on your computer? (which one are you plugged into)

Are you using ASIO as your driver mode in Sonar?

If using ASIO, please provide the settings for:
     Audio interface: Sample Rate and Buffer Size

     Sonar: Sample Rate, also what is the total round trip latency showing as?





Please answer all of the above,

here are his specs (copy pasted from other thread)

i7-3770
8GB RAM
NVIDIA GeForce GT 620
RME Babyface
UAD 2 Quad-core

SW: Win7 Home Premium 64-bit Service Pack 1
Sonar X2 Producer Build 306 [NOTE Mar 3: Now updated to X2a]

In this piece, VST: Zebra2(x64) two instances
PSYN II one instance
UAD 1176LN three instances
UAD Realverb four instances
UAD Pultec one instance
UAD LA2A one instance
Cakewalk Multivoice Chorus/Flanger one instance
Cakewalk Channel Tools one instance

like I said in the other thread, what plug ins are you using before you start the crash?
I would do a test by running all cakewalk synths and plug ins in a small project,
see if this works.(are you running both versions? 32 / 64 ?)
stick with 64 bit plug ins only if your running 64 bit sonar, this is only a test don't worry.
you may find one of your third pary plug ins are not playing nice in sonar.

I told you to check this before,so give it a shot please  :)
 
by the way no need to disable the realtek or the nivida,
I have both as well and they stay on all the time
disabling your soundcard is for only in cases you have an onboard soundcard pluged directly in to the motherboard.
you have a a break away box (term used by some) it plugs in usb, there for not as much a conflict, sonar see's this no problems.

Thanks - it is certainly helpful to have the mental picture of the system specs.  Many times, the basic specs are most useful for determining and resolving performance issues - in this case it is crashing altogether, so I need the additional info from the original poster, to try to see what is not playing nicely together on his computer.  

Barring a true hardware error, such as memory problems or intermittent disk failures, it would seem that good places to look for resolving this would be: Driver issues, Windows maintenance issues, settings mismatch on sample rate between Sonar and the interface, and/or a USB 2 audio interface having trouble with whatever port it is plugged into.  (possible problem with an individual USB 2 port, or perhaps the interface drivers freaking out to being plugged into a USB 3 port).  

It may be also project-related, such as a third-party plugin, and all of that, but going through that is a separate process, and in addition to reviewing the responses to my earlier questions, and one that mostly involves the original poster wading through things like loading one plugin at a time and such.

So, to the original poster, please review the above, and respond to my earlier request for specific information, so that I can better assist you.

 Thanks to all the responders!!--took a short Spring Break trip, back and still crashing http://forum.cakewalk.com...e/image/mIcons/m13.gif

I did run a disk scan early on, no problems. Haven't done a Memtest, but if I had RAM troubles, I would expect other software to be affected, not just Sonar X2a. What version of Windows? (7/8/etc) Win7 Home Premium, Service Pack 1 32/64 Windows? 64-bit Is Windows up to current maintenance levels? Yes. I do all Windows updates. What audio interface do you have? RME Babyface For your audio interface, what exact driver version are you using? Driver Version 1.0.18.0, by RME, date 12/15/2011, signed by Diplom-Physiker Uwe Kirst

In Sonar Audio-Driver Settings, I'm showing "ASIO Fireface USB Analog 1 (1) If your audio interface connects through USB, are you plugged into USB 2 or 3 on your computer? (which one are you plugged into)I have been plugged into USB 2 (black, rear panel) all this time. My USB 3 ports are blue, on the front. Are you using ASIO as your driver mode in Sonar? Yes If using ASIO, please provide the settings for: Audio interface: Sample Rate 48 kHz and Buffer Size 128 samples Sonar: Sample Rate, 48 kHz also what is the total round trip latency showing as? 7.8 msec, 374 samples. I started off with 64 samples in the "Fireface USB Setting - Buffer Size (Latency) settings, adjusted to 128 after first crashes, no apparent effect.

What happens if you increase buffer size to 256 or 512?

Hi,
if crashing happens repeatedly,
ram and power adaptor are often the reason.
350 Watt aso are not strong enough.
Better also stabilized........
