There is a sporadic ticking noise in the DUO's audio signal. When zooming into the waveform when it occurs it seems that a few samples (~8-10) are at approximately zero level:
Maybe the audio buffer is not fed quickly enough, or some buffer roundoff is happening. It's hard to reproduce and hard to notice as it's only about 0.2ms and only audible when a wave is somewhere in the top or bottom region.
