tehachapifan,
Thanks for response. Yes, I am using LP 5.014 and the sound file is S0556. The firmware version is 5.3.122 and is dated 6/8/2020. The Lokprogrammer shows that firmware as being supported.
Have no clue as I have attempted to reset decoder, reload the sound file, write changes to the file and all I get is the "selected decoder not supported". I am ready to give up on ESU sound. Too complex for a hick like me. I just want to run my trains not tinker all the time.
Regards,
Carl
