Hello,

My audio tracks don’t start at the beginning, but rather start at the 3rd or 4th second from the beginning. So I lose the first few seconds. Is this normal?

I use this very basic script

#include \<Wire.h\>

#include “SparkFun\_Qwiic\_MP3\_Trigger\_Arduino\_Library.h”

MP3TRIGGER mp3;

void setup() {

Serial.begin(9600);

Wire.begin();

mp3.begin();

mp3.setEQ(2); //EQ is 0-normal, 1-pop, 2-rock, 3-jazz, 4-classical, 5-bass

mp3.setVolume(12); //Volume can be 0 (off) to 31 (max)

mp3.playFile(7);

}

void loop() {

}

\*\*I have the same delay of a few seconds with the examples provided with the library.

Does the SD card being used happen to be an older model? Try changing to a different card and see what happens

My SD card is new. I tried with a different card and I had the same delay.

My mp3 file is 5 seconds long = 2 seconds of silence, 2 words for 2 seconds, 1 second of silence. It it starts to play from the 2nd word.

When I change the first 2 seconds of silence for 2 seconds with music, it seems to work well and start from the music and I have all my 5 seconds of audio content.

Could there be some kind of bug with “silence” at the start of the tracks ??

Thanks

On the back of your board beside the SD card holder there’s a chip.

Can you tell us what numbers and letters are printed on the chip?

Difficult to read, but I believe it is ±

I found this code in the seller’s page : DEV-15165

Strange ?!

Yet everything else is working fine. When I use the Example5-KitchenSink, I can control the board with the various Serial.available () commands. My only bug is that the “silences” at the beginning of the tracks don’t seem to be taken into account, and the tracks start playing after them.

I bought the board in a specialized electronics store in Montreal …

1. Do you think I can ask them for a refund.

2. Will Sparfunk reimburse the store afterwards?

Thanks
