I'm running an MSI 64 bit motherboard, with an intel quad

I'm not doing any parameters, just, "aplay filename.wav".
The -l options returns:
**** List of PLAYBACK Hardware Devices ****
card 1: Intel_1 [HDA Intel], device 0: ALC887-VD Analog
[ALC887-VD Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
I hope there's a clue in there somewhere.

Check your PCM devices with aplay -L
Probably the default device is badly defined.
And I think this should work:
This gets:
aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

This gets me the same error msg, i.e.,

Near as I can figure, it seems to be an improper device name,
but I have no idea how to track that down, or where it might
be.
