WHY DFPlayer mini DOES NOT PLAY AUDIO PROPERLY WITHOUT 3 SECONDS DELAY???

Hi Everyone,

                      I have been trying to play multiple audio files through DFPLAYER mini but when I play audio files without delay of 3 seconds I got distorted audio. I did as follows:

1.Set volume to full i.e. 30.

2. Play 4 audio files consecutively with 3 seconds delay after each track and all 4 audio played properly.

3. Then I play same 4 audio files but this time I removed all delays between them i.e. I play all 4 audio without any delay and I hear distorted audio. 

Does anyone have successfully play multiple audio files consecutively without delay using DFPLAYER mini module???

if so please comment and let me know.

Thank You
