Did you miss this part of the aplay -L output?

Just ignore this entry. alsa-lib tries to parse the all possible outputs that are provided from the kernel interface. Due to historical reasons, this digital output might be either SPDIF or HDMI, and alsa-lib has no knowledge to distinguish easily, hence both spdif and hdmi device names are provided equally for such a case. Again, on your machine, the HDMI output is the card#1, not card#0. The hdmi alsa-lib definition for card#0 is nothing but an alias of the general digital I/O.
