white noise from SPK HAT
lkebin opened this issue · comments
Hello, I'm try to test audio on M5StickC Plus with SPK HAT, using [WebRadio_with_ESP8266Audio.ino] example.
How can I avoid the white noise ? or is it expected from design ?

Hello, @lkebin .
There is a hardware circuit problem, which has been resolved in the newly manufactured ones.
If you have soldering skills, you can reduce noise by connecting a capacitor to GND.
Cool, let me have a try. Thank you !
Better than before, Thanks.
