Adafruit WAV shield - SD card init failed

Other Hardware Audio
1

Question:

I have built the Adafruit WAVE SHIELD and cannot get he SD card to initialize. All component pieces were purchased within the last few weeks from Adafruit, and I have done all suggested fixes three times, including altering the suggested sketch lines and library file. The card is a SanDisk 4 GB, formatted as suggested in the Adafruit instructions. I have tried several WAV files 7 the SD card works perfectly in the computer. Although this is not my final project, for testing purposes I pasted the uncompressed Pumkin Sound WAV files onto the card (and I also tried the other example files in the waveHC library top folder).

I continue to get the message "Error: Card init. failed! SD I/O error: 1, 0". Although the dapHC.pde and other sketches compile, upload to the UNO, and run. On one computer I also get an error message saying "Invalid library found in C:\Users\Dell User\Documents\Arduino\libraries\arduino: Missing 'author' from library." But the init error occurs on both computers.
Suggestions?

Thanks in advance, Dr. Prete

I'm having the same problems. Did you find an answer?

I am having the same problem with "Missing 'author' from library." I am using an adafruit FLORA. Have you been able to solve this problem?

I am not familiar with the FLORA...

but you are using the Adafruit Waveshield to connect it to? (maybe link to FLORA?)

from my experience...

SD cards not initializing is usually due to several things:

1.) Check all solder joint.. make sure there is enough solder to make contact and no COLD joints.

2.) Ensure all chips are inserted correctly in the WaveShield.. (I have seen time after time where main IC's are inserted the wrong way)

3.) Have you tried an alternate SD card? Not only brand.. but also size.. try some under 1GB cards to see if the react any different.

Have you searched or posted over at Adafruit forums to see if this 'missing author' error has been discussed over there at all?

Arduino: 1.6.6 (Windows 7), Board: "Arduino Leonardo"

Missing 'author' from library in Arduino\libraries\Firmata

But arduino-1.6.5-r5-windows works fine

Perhaps the library requires 8.3 filenames?
