Problem w/ Minim and Ess - Jack Router conflict?
May 14th, 2009, 9:42pm  
I've just started working with sound libraires and processing and it could be a n00b thing but I'm experiencing the same problem using both Minim and Ess.

The error is as follows:

2009-05-14 23:37:12.061 java[3169:19103] Error loading /Library/Audio/Plug-Ins/HAL/JackRouter.plugin/Contents/MacOS/JackRouter:  dlopen(/Library/Audio/Plug-Ins/HAL/JackRouter.plugin/Contents/MacOS/JackRouter,
262): Library not loaded: /Library/Frameworks/Jack.framework/Versions/A/Jack
 Referenced from: /Library/Audio/Plug-Ins/HAL/JackRouter.plugin/Contents/MacOS/JackRouter
 Reason: image not found
2009-05-14 23:37:12.064 java[3169:19103] Cannot find function pointer MyFactory for factory FAFCAFC3-BAE8-11D6-B4A8-00039315CD46 in CFBundle/CFPlugIn 0x1d6880 </Library/Audio/Plug-Ins/HAL/JackRouter.plugin> (bundle, not loaded)

It occurs when:
  • initializing Ess: Code:
    Ess.start(this);
  • calling Minims loadfile(): Code:
    player = minim.loadFile( "groove.wav" );


Any thoughts why Jack Router is apparently conflicting with these two libraries?

BTW, compiled applications using both libraries appear to work on this machine -- something specific to compile time I suppose?

Thanks!

In this case the most obvious solution was the correct one: backup and remove the file causing the conflict. Not sure what the long term effects will be but then again I don't recall using Jack Router in the past year so it's probably fine.

However, this did not fix my other problem: no audio would play. I figured the the audio output problems were related to the above conflict: apparently not.

But I took nillion42's suggestion from the thread "Minim problem... I can't hear ANYTHING" (I would post a link but apparently Im not allowed to yet)

Where nillion42 suggests
"Go to /Library/Java/Extensions  and take the two files called libMandoMixerOEMAJNILib.jar and libMandoMixerOEMAJNILib.jnilib, move them to some other directory, restart processing and try again. "

This suggestion worked for me.
Hopefully this information will help someone else encountering these problems. Please elaborate if you know a better fix!
