System crashes ASIO

Post by winger »

My system has 1 scope(15dsp) pci, and 2 pulsar 2 cards and I am using ASIO. Simple setup. Primarily audio i/o. I am developing audio software with JUCE, and any program using scope asio that crashing will cause an BSOD andreboot. Very painful when debugging software. Solving problems takes a long time when you have to reboot and reload everything when something goes wrong. This is not limited to my code. Trying to use Jack for windows can cause this. Even Sonar though it is quite rare with it.

I have 2 similar systems and they both have this issue. On windows 7 if I got caught an execption with the debugger, I could terminate scope before stopping debugging I could sometimes avoid the BSOD. I am now running windows 10 on my main development system and it does an immediate reboot (No BSOD) and I get no chance to prevent it.

Been a while since I actual got a BSODs but I think they always pointed to the scope.sys. I believe the it is related to ASIO drivers.

Anyone know anything about this?

Thanks, Mark

Might portaudio.dll be the common issue? I have struggles with portaudio with Scope.

Re-running the Scope installer can help...

Guess you could try upping the ulli rates in scope ASIO too. And check for irq sharing. I improved stability I believe when I disabled some devices sharing irq with Scope.

When asio crashes, always go to the task manager (to the services) and force quit scope.exe before pressing ok to the
"this app has crashed" window. This should help with the bsods.


I' m using win 7-32 bit.

Portaudio has nothing to do with it, that is jack. This has been happening without jack. If jackd crashes I get the same problem I get with any other ap.

This worked with windows 7, but in windows 10 I get immediate reboot. No app has crashed dialog, not even BSOD.

That's a pity.

Perhaps you can develop in a win7 system everything asio related and then test in win10?

With bsod's during development it must be a nightmare...

Remembering when I got the errors caught in windows 7, it was the scope driver writing outside of the memory space. My guess is when the app crashes, the driver does not know and still makes the callback for audio data. I've never written a driver, but it seems to me the driver needs to catch the exception and quit to avoid the bsod.

An app crashing should never cause the os to go down, and neither should drivers.
