Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

BSOD crash upon loading a particular app; unplugging headphones from WMR device avoids the crash

I'm wondering if anyone here has experienced anything like this crash before and/or have some ideas on how to fix it. The basic summary is:

  • The crash occurs for EXA (my VR music app) but not other apps
  • It doesn't occur for my WMR device (which doesn't have a headphone jack), but it does occur for other users (who have different devices)
  • The crash occurs immediately upon startup, and results in blue-screen-of-death
  • The only useful debugging info was found within a memory dump, which pointed to usbaudio2.sys as the cause of the crash
  • Unplugging headphones from the WMR device avoids the crash, which also points to an audio-related issue

My best guess is that it's related to EXA's custom audio system, probably at the time when initializing the audio device (this occurs outside of Unity, in a C++ DLL that uses PortAudio). EXA uses low-latency settings when initializing audio devices, so maybe the WMR audio crashes when a particular combination of settings is used?

Does anyone have any technical knowledge/experience about WMR audio... or can point me to someone who does?
