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:
# 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.
Audio software for Linux!
