Used Decoder Pro to change two Athearn GP38-2 locos from address "03" to their four digit road numbers.? However, on both locos the sound was removed but the locos operated with lights. Soundtraxx advised doing a factory reset (CV8=8) on my DCC (Digitrax) layout.? They suggested that JMRI Decoder Pro can sometimes change unwanted CV's.? Following their advice both locos returned to normal with full sound effects. I have not had this problem before with a variety of sound equipped locos. What am I doing wrong?
My JMRI set up is -- Windows 10, latest versions of both Java & JMRI, dedicated separate programming track, Digitrax PR3 with 18 V 1.5 AMP wall wart.
Thank you, Charles Millar
