Question:
Why does my N4321D lose audio after an extended period?
Why does N4321D lose audio if left running on the same source for over 30 days?
Answer:
A counter overflow condition was discovered in firmware, which would lead to a loss in audio if the source audio stream isn't switched for a period more than 30 days. This is resolved by loading v.1.6.3 or later firmware.
