Hello Everyone,

My setup is brand new Teensy 3.2 and brand new Audio Board. Headphones plugged into the headphone jack.

When I upload File > Examples > Audio > Synthesis > Guitar it plays and I hear it on the headphones.

When I upload File > Examples > Audio > HardwareTesting > SdCardTest and i put on the Sandisk Ultra 16GB SD card (Fat 32) the 4 files located at http://www.pjrc.com/teensy/td_libs_AudioDataFiles.html , I get :

Code: 
SD Card Test

SD card is connected :-)
Card type is SDHC
File system space is 15923.15 Mbytes.
SD library is able to access the filesystem

Reading SDTEST1.WAV:
  Overall speed = 0.91 Mbyte/sec
  Worst block time = 1.14 ms
    39.19% of audio frame time

Reading SDTEST1.WAV & SDTEST2.WAV:
  Overall speed = 0.79 Mbyte/sec
  Worst block time = 2.46 ms
