Using speaker from Chipsee cape(BBB-EXP-C) on BBB to play a sound

[radova...@gmail.com]

Hi,

I have BeagleBoneBlack(revC) and this capacitive touchscreen from Chipsee (BBB-EXP-C): https://www.electronicsdatasheets.com/manufacturers/logic-supply/parts/bbbexpc

I would like to use speaker from Chipsee board.

aplay -l

But it can be AUDIO OUT from BBB board, I don't know.

aplay /home/debian/sound.wav

Playing WAVE '/home/debian/sound.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

... without any error

But I cannot hear any sound.

Thanks for any suggestion.
