Linking to older versions libjxl gets the demo to play a sound...

sudo ln -s libjxl.so.0.8 libjxl.so.0.7
sudo ln -s libjxl_threads.so.0.8 libjxl_threads.so.0.7

However, it only plays once. When pressing "speak" subsequent times, no sound.

Could you please activate debug logging on the server and post the full logging, maybe then I can see what's going on.
