[[Unity] 2nd order ambisonic silent with Vive3DSP ambisonic decoder]

Hello,

Playing 1st order ambisonic works, however my 2nd order ambisonic file is silent when Vive3DSP Spatialiser is set as the ambisonic decoder.

Here are the steps to reproduce the issue:

1) Create a new Unity project (I tried 2019.4.17, 2019.4.21 LTS and 2020.2.3)
2) Import this 2nd order ambisonic audio file
3) Click on the audio file to show the inspector window
4) Tick the "Ambisonic" check-box
5) Play the audio preview in the inspector - you can hear the audio

6) Import Vive3DSP_v1.2.2.0 package
7) Set the Ambisonic decoder plugin to VIVE3DSP (as prompted by the Vive Input Utility window)
8)Play the audio preview in the inspector - audio is silent
8.1) Play the 2nd order ambisonic audio in the 0.3DSound(DistanceMode) scene - audio is silent

9) In Edit > Project Settings > Audio, set the Ambisonic Decoder to "None"
10) Play the audio preview in the inspector - you can hear the audio again
11) Set the Ambisonic Decoder to Vive 3DSP spatialiser again
12) Play the audio preview in the inspector - audio is silent again

Is Vive3DSP Spatialiser not supporting 2nd order ambisonics?
I couldn't find this mentioned in the official documentation.

Thank you for your help @Professor 3DSound

 

[[Unity] error CS0117: 'Environment' does not contain a definition for 'GetCommandLineArgs']

Hi,

After further investigation, we found the problem.

There was a custom Environment class in the project - which conflicted with the .NET System.Environment class.
Renaming our custom Environment class to a different name solved the problem.

I'm leaving the solution here in case someone else runs into a similar issue.

Thank you for your help
