Another problem? Not reassuring.
BTW: Since December, Im still waiting for Microsoft statement about audio
driver for WIN10.
Can you (or someone who knows) confirm that HLK certification process work
100% with SYSVAD audio driver example now ?
I will maybe have a time slot in June/July to rebuild a SYSVAD example and
test it in HLK Certification process

Devendra was running RS4 already when he grabbed the logs, so this is
something else.

Hello,
Its maybe about the virtual memory management bug reported in this list in
February 2018, producing big interruption in Real Time process

Scheduling/DPC Latencies on Windows 10
As it turns out, I had already started to update Windows (from 1803 -> 1809)
while working to collect more information. So I let it finish the update.
But now, after the update, I'm no longer able to duplicate this behavior!
Either there's something related to this that's fixed in Windows (or other
drivers which got updated alongwith), or maybe some other driver which was
causing this behavior is no longer being loaded.
I will keep checking. Sometimes this issue takes longer to reproduce.
Thanks.
Devendra.

Thanks. Im looking at the logs, and I dont see any calls into the Windows
audio stack. So the Microsoft.Windows.Audio.KernelStreamingEndpoint/Glitch
events I was hoping to see, that would tell me where to look, arent being
induced.
Can you add logs (you can reuse the same problem report) of audio glitching
from an app that uses the Windows audio APIs say, Chrome?
