Amazon echo TTS does not work anymore

For some weeks I am trying to figure out why the amazon Echo Control TTS functionality does not appear to work anymore. There are no errors in the log and the only somewhat strange behavior I found in the events log
here my rule snippet:

  items.getItem("EchoBedroom_Speak").sendCommand('please say soemthing');
  sleep(100);"'Good night' message #" + a + " read");

sleep statements have been added to force sequential execution, makes no difference though…the events log is as expected for the volume changes (and Echo reacts to those), what puzzles me is the last state change for the TTS channel, where it changes to a blank string (notice the void after “to”)

Any and all ideas are welcome.
I am running OH3.3.0 on proxmox, just re-installed the echo binding as well. I have no recollection that an update or similar rendered Echo mute, I remember it to simply stop working…

Hi Markus, unfortunately I don’t have a solution for you, but wanted to let you know that you are not the only one with this problem.
Until this is fixed, I have created several routines in the Alexa app which I start using the startRoutine channel and which speak the text.
