Hello,
I recently purchased a teensy 3.2 and the audio adaptor board. I have been unable to get the audio board to recognize any of the three micro sd cards I have tried despite all efforts. All three cards are SanDisk. One is an older 256 mb card (class unknown). The other two are both 32 gb class 10 SanDisks (one of which I purchased brand new today). I have read through many of the posts on here about issues with micro sd cards. I have made sure to erase duplicate instances of SD.h, I've reformatted each of the cards in every way possible (using both the windows 10 format function and the official SD Card Formatter application linked). No matter what I try, the Cardinfo sketch always says the same thing:
Initializing SD card...Wiring is correct and a card is present.
Card type: SDHC
Could not find FAT16/FAT32 partition.
Make sure you've formatted the card
And I am unable to play audio files (tried both.WAV and .RAW) from the Examples audio tutorial sketch Part_1_03_PlayingMusic. I am at my wits end trying to figure out why this seemingly simple task will not work. I've used all three SD cards successfully with the DFRobot .mp3 player and the Adafruit VS1053 audio board.
Any advice or suggestions about what I can do to get this board to read an SD card (or if anyone can tell me what I'm doing wrong) would be greatly appreciated. This is my first time using a teensy, so I readily admit that I may be making a very simple and obvious mistake somewhere. Thanks in advance for your help!
