Hi Eric,
recently, Alex Ratchov (of OpenBSD's sndio) has added a diff
to src/sndio.c that enables a finer setting of the desired
parameters of the underlying audio (namely, bit width).
Currently, the diff (attached) exists as a patch to the OpenBSD
port of SoX (which I maintain). Would you please consider
incorporating this change into SoX directly?
Thank you
Jan
