Jim,
I uninstalled Jplay and the exact same problem exists: my CAPS2 crashes and has to reboot at the end of a play if I use Kernel Streaming.
The problem does not exist when I use Wasapi Event. I would just use Wasapi Event EXCEPT THAT WITH MY SYSTEM KERNEL STREAMING PRODUCES THE BEST SOUND. You have a product that can sound very good, but in my system it only sounds best with Kernel STreaming.
I am using JRiver and computer audio (a CAPS2 music server) because I have found that indeed computer audio CAN sound better than the best transport I have heard. (I use an Accustic ARts transport, but have tried many over the years.) PLease help me resolve this problem, so I (and others) can get the best sound possible.
By the way, the one truism I have found in 30+ years of audio is that "everything is system dependent". If you have a very highly resolving system, as I do, you will notice things that others do not (eg, that KS is better than Wasapi Event in my system). Indeed, I just changed interconnects from STealth to MIT Oracle Matrix and have been able to hear even better the difference between KS and Wasapi Event.
