Hi,
When opening the MRTK3 magic leap fork, from [GitHub - magicleap/MixedRealityToolkit-Unity at mrtk3\_MagicLeap2](https://github.com/magicleap/MixedRealityToolkit-Unity/tree/mrtk3_MagicLeap2) — there’s an error that the Microsoft Spatializer Mixer cannot be found.
A screenshot showing the same error is included in this GitHub issue: [Default spatialization audio mixer throws errors when Microsoft Spatializer package is not installed · Issue #11349 · microsoft/MixedRealityToolkit-Unity · GitHub](https://github.com/microsoft/MixedRealityToolkit-Unity/issues/11349)
Does anyone know a solution or workaround? Thank you

Do we need to follow these additional steps to get it to work?

Best regards

I recommend trying this out to see if it works.
I have reached out to our team regarding this issue and I will report back as soon as I learn more.
Best,

Thanks, @etucker -- I just had a look and the "Mixed Reality Feature Tool" downloader is a Windows .exe only, so I won't be able to use it. (I'm on a Mac.)

Here is a potential workaround:
Try to build the project 3 times. If it fails, Try to build one more time and it should build anyway.

This is a known issue and we are hoping to release a fix in the near future.

Hi @etucker
It looks like with a new clone of
```auto
git clone --branch mrtk3_MagicLeap2 https://github.com/magicleap/MixedRealityToolkit-Unity.git
```
this workaround is no longer working.

Actually I was able to get it to work by unclicking
XR Plugin Management\>MagicLeapSettings\>"Enable ML Audio"
and by checking
Project\>Audio\>"Disable Unity Audio"
