I2S with MAX98357A like a robot #17

Hi,

Sorry, my english is not my native language. So I'll make short sentences

I'm trying to test the I2S with your firmware and examples:

I have sound coming out of the speaker, but it's not audible, like a robot. I use MAX98357A 3W board

I made the same connections as your Hardware Test Setup: bck_pin = Pin (21) -> BCK board ws_pin = Pin (22) -> LCR board sdout_pin = Pin (27) -> DIN board

SD board -> nothing Gain board-> test GND or VCC

I used your example: play-stereo-wav-from-internal-flash.py

I tried changing some setting, but it doesn't improve the sound.

Can you tell me what I'm doing wrong?

Thank you so much

It's my mistake. The speaker I am using is not good. I changed it and it works great. Thank you
