After a few weeks of good functioning speakers, Voice Monkey stopped outputting to Text to Voice my Alexa devices. I deleted all voice devices, disconnected the skill, reconnected the skill and successfully synchronized 2 "new" devices using newly created routines.
Using the API on these devices, I get a RC of 200 for the API but still no voice feedback. Playground doesn't produce voice feedback either. If I run the involved Alexa routines manually, I get the "new device added" message that was pushed to them during synchronization. Anyone any clues on how to fix this? Is it a bug? Any help is welcome.
