aplay supports stereo files; whether the driver supports this depends
on the driver.

I don't know what you problem is, but it's likely that you tried to
play a stereo file on a mono device or a mono file on a stereo-only
device, and that you used a device name like "hw:0" that disables all
automatic format conversions, instead of "default".
