kAudioUnitID_DLSSynth and Snow Leopard

HI,

I assume it's now OK to ask questions related to Snow Leopard.


The code snippet below fails with kAUGraphErr_InvalidAudioUnit = -10864
on Snow Leopard. I has worked OK since OS X 10.2 up to 10.5.8


ComponentDescription description;

  

// Create the graph
XThrowIfError(NewAUGraph(&m_graph), "NewAUGraph() failed");

   

// The DLS Synth
description.componentType = kAudioUnitComponentType;
description.componentSubType = kAudioUnitSubType_MusicDevice;
description.componentManufacturer = kAudioUnitID_DLSSynth;
description.componentFlags = 0;
description.componentFlagsMask = 0;

 

XThrowIfError(AUGraphNewNode(m_graph, &description, 0, NULL, &m_synthNode), "AUGraphNewNode() for synth node failed");


Is this a bug in Snow Leopard or do we need to do something else on Snow Leopard?
I assume kAudioUnitID_DLSSynth is still supported.

Thanks,
Rolf
