PROBLEM TO BE SOLVED: To provide a digital audio reproduction device that continues reproducing even after reproduction data in a memory are corrupted, and extends the time until a system fails. SOLUTION: The digital audio reproduction device 10 comprises: a storage part 230 connected between a digital audio input source 1 and an output device 2; a reproduction signal writing part 231 which writes into the storage part a reproduction signal input from the digital audio input source in synchronization with a first clock (clock supply source 12); a reproduction signal reading part 232 which reads the reproduction signal from the storage part in synchronization with a second clock (clock supply source 22) which is more precise than the first clock driving the output device; and a reproduction signal monitoring part 233 which monitors the reproduction signal written into the storage part, and when the reproduction signal satisfies a predetermined condition, initializes the storage part and writing and reading addresses to the storage part.
