It looks like an audio clip is only getting sent to the device when the audio state is toggled.
These are the logs at the moment I cancel the settings dialog after 10s without audio that makes one sentence to be read out loud:
Code:
[10.45] Audio state: State.IdleState
[10.45] Utterance 1 audio output finished
[10.47] Audio sent to output: maxlen=16384 len(ans)=16384
[10.47] Audio state: State.ActiveState
At all other times, all I see I see is piper zooming through the synthesis and "Waiting for audio to finish playing..." with no errors but no sound or "audio output finished" messages e.g.
