Stream url mp3 to speaker 100w ( Amp built_in)

[vplong990]

I can stream mp3 (128kbps) to ESP32 with PCM5102A and 5w speaker no problem, but when I tried to use 100W speaker (amp built in) , the music seem delay short time ( ~ 0.1s) in during stream. Sorry my bad English.

I would expect that mp3 is adding more delay then wav due to the internal buffering.

Note that I don't know how much delay your hardware components are adding.
