I found this on the net... Could it be related?

*Problem:*
Aplay/mplayer only plays 48000 Hz stereo files, saying "[AO_ALSA] Unable to
set hw-parameters: Invalid argument" and "aplay: set_params:961: Unable to
install hw params:" irrespectively. No mono and no non-48kHz files work.
*Cause:*
Alsa doesn't know how to resample, but doesn't mention that even when you
specifically ask it to in .asoundrc.
*Solution:*
Rebuild alsa-libs to include all the pcm plugins. In Gentoo, this means
sticking ALSA_PCM_PLUGINS="*" in make.conf and emerge alsa-lib.
*Reason:*
Alsa should now be able to resample audio and magically play all the other
formats, even without ~/.asoundrc or /etc/asound.conf
