The Mini MP3 Player of LB0007

The Mini MP3 Player of US0014

Firmware versions:

[ForrestErickson]

Lee swapped an MP3 player with a TD5580A into US0014.
Lee discovered that an "a3" message did not not make audio. The 125Hz tone should have played.
The different behavior above correlates to the no audio on TD5580A Mini MP3 Players.

Setup notes.
SD Card Files:

[ForrestErickson]

Lee tested US0008 which has a TD5580A Mini MP3 player.
