There is no 100% certain way, so far. A practical way would be to open analog then SPDIF PCMs at the same time with non-blocking mode. If both can be opened, it's likely non-duplicated one. Or, we can change the "default" PCM to always output both. Not sure whether it's a good change, though. But usually SPDIF output can be turned off via a mixer switch, so this wouldn't be a big problem (I hope).
