DUDU-Meng After testing with different options in the Amigo app, it seems that, when setting up any voice built into Amigo, the sound is mixed correctly and playback is not stopped. However, if Google's text-to-speech (TTS) engine is selected as a sound source, playback is interrupted. Everything indicates that the problem is that, although the Amigo application is marked for mixing in Dudu, using Google's TTS forces the stop of the playback.
