aplay can't handle anything but straight PCM formats. in addition, using
hw:XXX means that the requested data format MUST match the hardware
capabilities. if you ask for a sample rate or channel count not supported
by the hardware, the device configuration will fail. this is why the
"default" device with ALSA is never hw:XXX but at minimum plughw:XXX (which
can do just about any format conversion necessary).
