TomC OK, so you stop playback within a song, then select a new song. The song title in the player changes, but lyrics are not loaded and the waveform view does not switch to the new song. Is that correct so far?
Then when you press play the button changes to pause but nothing happens. Right?
What happens when you then select another song?
Would you be able to make a short movie of the situation? I guess that would help me understand better where exactly it fails.

I will publish a new version there today once I understand what is going on. From what you write, this might not be an audio issue but an issue with song selection.
