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.
Not here, they aren’t. There is no PCM named “spdif” at all: it isn’t in the list, and if I type it, I can’t play to it for a reason that looks a lot like it doesn’t exist.
OK, then another possibility is a BIOS bug. BIOS declares the pin as HDMI incorrectly although it's a SPDIF.
