Hello!

I am working with CS43L22 on STM32F407VG Discovery Board.

I use Audio_playback_and_record example to play .wav file.

If i use headphone, I can get good sound. But If I use speaker I get small sound.

Is that normal?

Aren't the speaker outputs of CS43L22 unconnected on the STM32F407VG Discovery Board?

Yes. I was consider STM32F407 Discovery schematic and CS43L22 Datasheet. You are right! Thanks you for your confirmation.
