HI, mic.read(samples) returns always 0 with the latest ESP32 lib. Please fix!

Thx!

looking deeper in this I found using I2S_CHANNEL_FMT_ONLY_LEFT at the constructor get it back to work fine :)

AudioInI2S mic(SCK_PIN, WS_PIN, SD_PIN, -1, I2S_CHANNEL_FMT_ONLY_LEFT);

Glad you were able to find that on your own. Not all MEMS microphones default to sending to the I2S_CHANNEL_FMT_ONLY_RIGHT channel, I just picked the default that worked with the ones I have.

I'll update the AudioInI2S Readme for some trouble shooting help.

Thanks
