What he said... ;)

Jerry:
Nice one :)

Just keep in mind each time you get a new kernel, you'll have to do the same again with the config file, or, just keep booting that kernel.

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

Jerry:
The /boot/config.txt is unique to the Pi.

Jerry.

i found this info at https://raspberrypi.stackexchange.com/questions/44/why-is-my-audio-sound-output-not-working

Sound does not work with an HDMI monitor :-

This is caused by some computer monitors which select DVI mode even if an HDMI cable is connected. This fix may be necessary even if other HDMI devices work perfectly on the same monitor (or TV)! Edit the /boot/config.txt file (see Raspberry-Pi Configuration File) and add the following line to the configuration file:

hdmi_drive=2

If you think this will fix my problem, show me How do i edit the /boot/config file ?
there is a warning on file saying automatically generated file do not edit
