This may be another clue: I reinstalled libsox-fmt-alsa, and with AUDIODRIVER unset, 'play foo.wav' issues a warning (before proceding to play successfully):
play WARN alsa: can't encode 0-bit Unknown or not applicable but 'play foo.wav -t alsa' issues no warning. I'm guessing the absence of -t <driver> affects the order of initialization, causing a warning for alsa and a SEGV for oss.
