I went to File System/boot and opened the latest file config-5.4.0-45-generic as administrator
on the last but one line i added
CONFIG_HDMI_drive=2
Then saved the file
After reboot normal sound returned on my Sony TV model KD-55XF7073
Audio mixer/volume control/configuration i selected
Digital Surround 5.1 (HDMI} Output
Digital Surround 7.1 (HDMI} Output
Both worked the Fault is cured
As a further test i deleted line CONFIG_HDMI_drive=2 then rebooted,
the tv did not revert to my original fault ie sound garbled sqeeky
Also because i run dual boot my Linux Lite v3.4 also has normal sound without the me needing to modify the config file
i do not fully understand what i have done. but i am happy that it worked
