The issue is a forced block of updating the reflector audio files.
This was put into place to protect the embedded nodes against a very large reflector WAVE file from flooding the flash disk.
This is not an issue any more, as the files for the reflector are added manually.
To allow your embedded node to play the audio files from the reflectors, you have to remove the words:
from the file
Then run the flash_sync command to save the change.
