Dave.....

Thanks for the key piece of information about what Kodi is looking for - ID3 v 2.4 tags. MP3Gain does not seem to produce this version of tags. When it's done the analysis and I look at the results in MP3tag it only reports APEv2 tags although it does show the Replaygain/Peak values.

If I then use MP3Tag to write out the tags I can set the option to produce ID3 v2.4 and once this is done Kodi picks up the tags and normalises the track volumes.

I don't know enough about this but are Replay tags also valid in other tag versions? If so could Kodi be programmed to be somewhat independent of tag version in this respect?

Many thanks for help in sorting this out. I now have the large task of adding the gain tags and then saving them as ID3v2.4. I need a rainy day :-)

Thanks again
