Porter Posted February 20, 2020 Report Share Posted February 20, 2020 I had a labivew application crash yesterday due to the PC running out of memory. Looking at the windows 10 system logs, it was audiodg.exe that ate up all of the memory. Re-launching the application again and triggering the beep sound caused audiodg.exe memory usage to shoot up at 10s of MB/s. I suspect that this is a realtek audio driver bug because I can't reproduce this behavior on my development machine. Has anyone else come across this kind of behavior before? Quote Link to comment
Porter Posted February 20, 2020 Author Report Share Posted February 20, 2020 Just tested beep VI on its own and again I get the same run away ram consumption of audiodg.exe (+5MB/s). I've got a bleeping memory leak! RAM remains reserved by audiodg.exe even after exiting the application. When using the sound VIs to play a WAV file, there is no such memory leak behavior.

This doesn't sound like a LabVIEW issue, so I'm not going to escalate it, but drop me a personal message if your ongoing investigation leads you back to NI. Quote Link to comment
