thank you for pointing this out to me -- this was indeed causing problems.

If anyone wants to help in testing, please try the snapshot at:
http://ecasound.seul.org/download/snapshots/ecasound-2.3.6-cvs-20041221.tar.gz

# the basic syntax is:
ecasound -f:16,2,44100 -i resample,auto,foo96khz.wav -o alsa 

# with samplerate's 'SRC_SINC_BEST_QUALITY' quality
ecasound -f:16,2,44100 -i resample-hq,auto,foo96khz.wav -o alsa 

Where 16(bit), 2(ch) and 44100(Hz) are the target audio parameters. This
should work with any ALSA/OSS, JACK, wav/aiff, ogg/mp3/flac/etc output.
