Hello, I would like to connect audio signal from pc sound card to SIM900 GSM module. I am using simple breakout board from Itead studio, I connected the grounds together and signal form sound card to board input. Only thing that I can hear is noise. If I connect microphone I am able to hear sound. Can somebody help me connect sound to this module ?
Thanks in advance !
