MRTK3 Template (ML fork) - Spatializer missing

paklnet · January 17, 2024, 10:21pm

Hi,

When opening the MRTK3 magic leap fork, from GitHub - magicleap/MixedRealityToolkit-Unity at 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

Does anyone know a solution or workaround? Thank you

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

microsoft/spatialaudio-unity/blob/develop/Documentation/QuickStart.md

# How to add the plugin to Unity projects

## 1. Add the spatializer package via the Mixed Reality Feature Tool
- Download the Mixed Reality Feature Tool from https://aka.ms/mrfeaturetool.
- Select the `Microsoft Spatializer` component from the `Spatial Audio` group and integrate the plugin into your project using the `Get Features` button.

- If you are using the Sample project in the repo, you'll need to import the MRTK packages listed below, in addition to the spatializer plugin:

The plugin package can also be downloaded from GitHub releases and imported into the project using `Assets > Import Package > Custom Package` menu.  

## 2. Configure the project to use Microsoft Spatializer
- Open the project settings using `Edit > Project Settings`
- In the `Audio` tab, select `Microsoft Spatializer` in the `Spatializer Settings` dropdown. No other changes are necessary.

Hi @paklnet,

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,

El

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

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"
