I have installed the version 9.510 of Navcore on and SD card with the latest Europe map.
All works fine...

except, I have no sound anymore.

I used to have this before but I can't remember what I had to do.

I replace the old LoquendoTTS directory on the new SD card and I replaced the old voices directory on the new SD card.
But that does not solve it.

Can someone please remember me what I have to do to get the sound working again ?

Thanks.
Stefaan

If you used the working folders from a backup your problem is not within the voices.
