NodeMCU ESP8266 LoLin using AudioFileSourceHTTPStream & AudioOutputI2S with MAX98357 I2S DAC

if I change line code:
from:
buff = new AudioFileSourceBuffer(file, 2048);

to this:
buff = new AudioFileSourceBuffer(file, 2048*8);

Error Code will change like this:

14:20:55.527 -> ...Connecting to WiFi

Plzzz help me solve the problem
