Adafruit MAX98357 I2S Class-D Mono Amp with Gameboy Zero

[tronicgr]

Hi,

Anyone is using the Adafruit MAX98357 I2S Class-D Mono Amp with his gameboy zero?

I added the I2S amplifier to it on the recommended pins, followed the instructions to setup the system to use it but when the only thing it does is low noise static, followed by silence when I play a sound. Any idea?

I use the latest retropie and haven't found any information is there is any incompatibility issue anywhere or any similar posts. I also connected the SD pin to a switch to turn it off in needed. Even when its not playing sound, I measured +350mA consumption, I soldered a second one I had just to verify it was not burned or shorted, but has same behavior.

Any suggestions are welcome

Thanks
Thanos
