Created a new stereo file (attached) as advised in Audacity, but still no output.
In fact the serial monitor is telling me:
Initializing SD card...initialization done.
Bits per sample = 8
Channels = 1
Sample rate = 88200 Hz
Duration = 0 seconds
unable to play wave file using I2S!
starting playback
playback stopped
Am I missing something? Audacity has never let me down before and It's always resampled/created files in the format/configuration I need, so I can only assume I'm doing something wrong here. Do you have a correct file I can try, one that does work on the Zero? If I can see it working with a file at least I have a glimmer of hope before giving this up as a bad job.
