Hello,

I am running RealSpace 3D Audio (v0.10.7) 18Aug15 on Windows 7 64-bit with Unity 5.1.3p1 64-bit. No matter what I try, I am unable to trigger sound playback via C# script code in Unity. When I check ‘PlayOnAwake’ the sound plays correctly, but if I uncheck that and use ‘rs3d_PlayIn3D(true)’ via code to play a sound sample, it will not play back. Is there a bug? I am a very experienced developer/programmer and followed all of the instructions presented, so it’s a bit baffling to me that sounds will not play. I’m not doing anything complicated, just attaching a RealSpace3D_AudioSource to a gameObject and trying to hear it played back through a RealSpace3D_AudioListener, attached to a gameObject that also has a Unity AudioListener on it.

Thanks,
Alex

Here is a log dump from my attempt to play back 3D audio samples via code. This is from my test scene, where I instantiate 4 prefabs with RealSpace3D_AudioSources attached and attempt to play a single sound back using the first RealSpace3D_AudioSource via script code. In this example, I pre-loaded the AudioClip into the prefab, to eliminate the loading step as a possible cause of the problem. The sound plays back correctly if I drag the prefab into the scene and check ‘PlayOnAwake’, but it won’t play if I use ‘rs3d_PlayIn3D(true)’ via code to play the AudioClip loaded into the RealSpace3D_AudioSource.

It appears that ‘rs3d_PlaySound()’ and ‘rs3d_PlayJukeBox(0,false,false)’ both work for me, but ‘rs3d_PlayIn3D(true)’ does not. I tried swapping in ‘rs3d_PlayIn3D(true)’ for ‘rs3d_PlayJukeBox(0,false,true)’ to trigger music files in the ‘realspace3d_v0.10.0_sample.unitypackage’ sample scene, and it seemed to work there, so I’m guessing there’s a bug with the (v0.10.7) 18Aug15 build. In any case, I can move forward now. Thanks for making such a fantastic binaural 3D audio solution.

Hello Alex,

Thanks for using RS3D Audio. Sorry about the confusion. The PlayIn3D actually should not be exposed. It is a method that is used internally to indicate play in 3D mode or not. It will not play sound. The PlaySound method plays the sound. The Jukebox is a feature that is still in beta and thus not documented in the API documentation. It works but just hasn’t been officially exposed. Thus, those 2 methods (PlayIn3D and Jukebox) should not be exposed. I will remedy that. 🙂

So, there is no operational bug. PlayIn3D toggles play the sound in 3D or not.

Thanks for the compliment. We appreciate it.

-Rod
