[ISSUE] Asio Guard crashing Cubase

  1. Create empty project
  2. Add an audio track
  3. Add another audio track
  4. Turn on Asio Guard - low / medium or high
  5. Enable monitor or record on ANY track
  6. All audio, VSTi output and metering is lost
  7. Cubase requires Windows task manager to quit

The same crash happens for ANY type of track - Audio / Instrument

Windows 7 (64) SP 1
Intel® Xeon® CPU E5-2650 v2 @2.60Ghz (2 processors)
128 GB RAM
Cubase 8.0.10
No 3rd party software
Steinberg MR816X FW driver v1.6.5 MR Editor v1.6.4 Steinberg FW driver utility v 1.1.0


It was not so catastrophic on my system, but also just refused to record when Asio Guard was on.
Had to turn Asio Killer off and records perfectly :slight_smile:

Hi Jon,

i could confirm your issue…
It seems to be related with dual-socket processor architectures!
I´m actually on the very same dual Xeon-Setup.

And it´s a C8 only issue - AsioGuard with 7.5 works fine.


Aloha guys just to chime in:

No probs with Asio Guard here.

Good Luck!

Hi Guys any update on this dual Xeon issue? Cheers

simliar issue here on pro 8.5 and single i5-2500k cpu… asioguard is a full on nightmare when it comes to audio tracks that are record/monitor enabled and trying to switch between them. for sure a bug of some sort.

I’ve got a similar issue right now. Was there a fix for C8.5 32bit?
