This is in fact a big problem. While soundmodem does have the resampling
code and is able to use any sampling rate above a certain minimum required
for the mode, some driver emulation layers interfere with this. ALSAs OSS
emulation layer is a culprit here, it's also quite buggy.

I've put a soundmodem version with a rather experimental native Alsa API
on http://www.baycom.org/~tom/ham/soundmodem/soundmodem-0.9.tar.gz
