I am trying to use this sound module, discussed here http://forum.arduino.cc/index.php?topic=150535.0
I am able to get it to play sound using the Arduino, but it ignores the messages from the Teensy 3. When I monitor the serial output from the Teensy 3 it looks the same as the Arduino. So not sure what I am doing wrong
This is what I tried
Connect to Teensy 3 power and use TX1, then TX2, then TX3 to send messages
Connect to Arduino power and use TX1, then TX2, then TX3 to send messages
Bought logic level shifter, used Teensy 3 TX's in and then the out to the sound module
Tested that power was coming through the logic converter using an LED and the rails on the breadboard
What does work is using Teensy 3 power and send messages with Arduino.
The photo might look a bit crazy, I started setting up my Teensy 3 to use with my other development, very few of the wires are in use

Pin outs in photo
Teensy pin 1 to sound module pin 17 (RX)
Teensy volts and ground to rail on breadboard
Sound module gets its volts and ground from breadboard
Sound module 11 to speaker
If I leave everything as is and just plug the Arduino into the RX I get sound, my Arduino is grounded to the breadboard. So the module is getting power correctly.
