Unity3D is recognized by Jack, but no sound is coming in.

Platform: Windows 10

I am trying to use the "send effect" example to send audio from Unity3D to MaxMSP. I can not get it to work. The moment I play my Unity3D game, the Jack Console fills up with errors: "JackEngine::XRun: client = Spatial Engine VR - WIN was not finished, state = Triggered". A complete stack overflow and all audio related apps crash.

I find this a strange behaviour because my buffersize is set to 1024. Other apps tranfer audio just fine. I suspect another kind of problem, maybe a mismatch of some kind? To the best of my knowledge, all the DSP settings are in sync.

These steps are taken:

• installed and registered jack 1.9.11, jack appears to be running normal and routing audio between programs is working fine.
• Jack Portaudio is targeting ASIO :: ASIO4ALL.
• I loaded the Example scene "send effect". This example seems to be the only one that does not crash instantly.
• Followed these steps to avoid a crash on startup: https://github.com/rodrigodzf/Jack-Audio-For-Unity/issues/15
• In Unity3D, I set the speaker default layout to mono. 48000 khz, and "high performance mode (1024 frames)"

In jack audio: I set my preferences to match 1024, 48000 khz.

My best guess at the problem: I am suspecting that the settings I tweak in the JackControl interface are not inplemented. When I navigate to: messages > status. I can see that the server is always running on 512 frames despite the fact that I changed it to 1024 and restarted the server.

Also: In MaxMSP, I can not set my vector size beyond 512 frames.

What could be the cause of this problem?

Kind regards, Marijn

I just checked in Windows, and it is working with the setup you describe (although using puredata instead of max, since I don't have max installed). My settings are these in jack:

You could try jack and max/msp independently from this plugin and see if that works

Hi,

I think maybe you should figure out why the JackAudio sample rate cannot be changed. Maybe you are using an unsupported backend. Apart from that, you could try with ubuntu, the plugin works there as well,

@rodrigodzf https://github.com/rodrigodzf I managed to specify the problem: more specifically:

I have notices that I am unable to change the samplerate in Jack audio, the settings don't w When I run Unity3D, the Jack audio server samplerate jumps to 0. This results in a crash.

@rodrigodzf indeed. I did get the samplerate to 1024 by defining it in port audio as a backend target property. This get's the setup to work.
