Topic: Drivers locked in audio development

Hi to all. I'm a developer and I workin on audio applications.
I bought a Digiface USB. Wonderful card.
There is a problem with drivers when applications crash. It appens when crash occures 4-5 times. Drivers goes in lock mode and the unique thing to do is switch off/on the card (in my case unplugging usb cable).
Moreover, after various lock the card doesn't respond anymore, even turning off and on. In this case I need to restart OS.
This happens on Windows 10 but I think on win7 too.
I've received confirm by another audio developer with same issues and another RME card (I think a fireface).
The problem it's not linked to card. It's a drivers problem.

P.s.
Just for information. It's an old problem. This not depends by last revisions.

P.p.s.
I can send a sample application with wrong code to test the crash.

I'm not aware of such a thing as "lock mode". Please be more specific about what exactly happens..

Please do so.

Let you know soon. I'm busy now.

Anyway, to better explain:
During software development it happens from time to time that the application crashes due to a code error.
After several crashes the drivers no longer respond and the card is no longer reachable.
I will attach a test application with a crash button so you can try to run it and simulate the crash multiple times. After several crashes the card stops responding.
Thank you.

Ok...I report a video below to show you what I'm saying.
I cannot replicate it using compiled exe maybe because the framework I'm using automatically complete the code cycle and close drivers correctly even if crash occures.
But in debug mode I stop the execution instantly.
This issue doesn't happens with other cards.

I will try to make an exe with native c ++ code to allow you to test the case

Re: Drivers locked in audio development

Did you do these tests with the latest 0.9723 driver? It has some improvements that might be of relevance here.

Re: Drivers locked in audio development

Problem still persist with last drivers.
It's not replicable in the normal using but it happens developing audio applications.
You can tell to RME developers to try to open connection to audio drivers in debug mode and cause a crash or stop application without release drivers.
After approx 5-10 times the drivers does not responds anymore.
Thank you
