Your DragonFly looks like mine, only accepts 24 bit word length.

Use plughw rather than he.

Thanks for the quick repsonse.

Now I can't get alsa to use the sync resampler.

aplay -v -D plughw:1,0 2-15_Route_66.wav
Playing WAVE '2-15_Route_66.wav' : Signed 16 bit Little Endian, Rate
44100 Hz, Stereo
Plug PCM: Linear conversion PCM (S24_3LE)
............

even though:

cat asound.conf
#
# Place your global alsa-lib configuration here...
#
defaults.pcm.rate_converter "samplerate_best"

and

ls /usr/lib64/alsa-lib/
libasound_module_conf_pulse.so
libasound_module_ctl_oss.so
libasound_module_ctl_pulse.so
libasound_module_pcm_oss.so

libasound_module_rate_samplerate_medium.so
libasound_module_rate_samplerate_order.so
libasound_module_rate_samplerate.so
smixer

What am I missing this time ?

Sean, what is it you are trying to do? Are you just trying to convert the
16 bit to 24 bit? Or are you trying to upsample as well?

If just 16 -> 24, can you explain why you want something other than linear?
