hiya,

I have the audio playing using JavaSound the format is...

AudioFormat audioFormat=new AudioFormat(Encoding.PCM_UNSIGNED,11024.0f,8,1,1,11024.0f,false);

using AudioSystem3D I tried the following...

AudioSystem3D buffer format only offers 4 states so I did a little digging in the structures and found that ALHelpers helps put formats together so I came up with this...

 private static int getFormat(int _channels,int _bits,boolean _signed,boolean _floatingPoint)
  {
  AL al=ALFactory.getAL();
  ALExt alExt=ALFactory.getALExt();
  int sampleType=ALHelpers.getALSampleType(_bits,_signed,!_floatingPoint);
  int channelLayout=ALHelpers.getDefaultALChannelLayout(_channels);
  int format=ALHelpers.getALFormat(channelLayout,sampleType,true,al,alExt);
  return format;
  }

Buffer.configure(bb,getFormat(1,8,false,false),11024);

but it didn't work. I guess the format in AL works different that what I have deducted from the JavaDocs.

maybe someone with more experience could see what is wrong.

thanks
