Hi,
Does anyone managed to configure google tts in ubuntu server?
It works for me very well on my mac, but on ubuntu (14.04 as well as 16.04 - Oracle java 8) although say command is processed without any error there is no sound.
Generally sound is working while using other applications.
Thanks for any response 
In meantime I discover that this problem appears in case of installation of openhab using apt-get install …
Does anyone know what to do next?
Maybe a track to follow is the user used by the apt get install which could differ from a manual install.
Personaly I stopped using goigle tts due to several issues described here:
Does it work when you run it from the command line using the openhab user?
sudo -u openhab <tts command>
Use full paths for the command and any arguments that are files.
If that doesn’t work the problem is almost certainly a permission one. You will need to give the openHAB user permission to make that call.
Rather not, both are the same.
