SparkFun Qwiic MP3 Trigger DEV-16892 no playing on triggers

Hi

i am hoping someone can stop me being very dumb

about a year ago a made a sound glove for a costume using the SparkFun Qwiic MP3 Trigger i now needed to make a couple more so ordered some direct but

for the life of me i cant seem to get these one to work out the box like before

so hoping someone can suggest some basics test to work out my issues

powered from 2XAAA (via GND and 3.3v)

i get the red light on

I have so far tried is

different mp3 files

different SD cards (the same SD cards in a WIG-13720MPĀ£ Trigger plays ok )

different SD cards sizes 1GB,16GB 32GB

different batteries

different boards (as i ordered 10)

files are name T001.mp3 ect etc

if anyone has any ideas they would be most welcome

bump for any ideas
