I have Mathematica 12.1.0.0. When I execute the command
Speak["Hello"]
I hear nothing. In the earlier versions of the software, Mathematica would 'speak' the words/string inside the 'Speak' function. How to fix it? My computer audio system works fine.
My OS is Ubuntu 20.04 focal (x86-64) (Linux Kernel: 5.4.0-53-generic)
$Version="12.1.1 for Microsoft Windows (64-bit) (June 19, 2020)"
