you should not need sync=false. Regarding audioresample, try
speexresample. Audioresample has been replaced by it in cvs. Its faster
and better too.

To understand you right, the wav file is 96kHz. At what sample rate is
your jack running? If its the same audioresample will automatically
become passthrough.
