Yes. "cat some.wav | /dev/audio" makes no sense. That basically means
"take the output of 'cat some.wav' and pipe it through the /dev/audio
program". Nonsense, since /dev/audio is a device node and not a program.
Mind you, "cat some.wav > /dev/audio" doesn't make any sense either. You
can't just write a wave file to the device node and expect to get sound: a
WAVE file is not just raw audio data. Investigate sox
(/usr/ports/audio/sox) - this will let you test out the sound properly
with WAVE files.

Actually, it's exactly what would be expected.
