Could you give pointers as to how to modify Alsa configuration so that rate conversion can never happen, as I would prefer to have an error accessing the sound card rather than unknown conversion, which in my use should never be neccesary anyway.
Simply open the hw device rather than the default, dmix, or plughw device.

Lee,
Are you saying that plughw *does* do hidden conversion? I thought its definition was equivalent to
newplug { type plug slave { pcm "hw:0,0" } }
It's not "hidden" conversion, by using the plughw device you are explicitly asking ALSA to convert the PCM stream to a format the hardware supports.
