Piping audio to GPIO

kkooler

Hello,

Is there a way to pipe audio signal from sound card to GPIO (perhaps PWM)? Raspberry automatically does that when PWM is enabled, but I can't get any sound from Orange after enabling pwm0 and connecting to PA05:

1. [pwm0_para]
   
2. pwm_used = 1
   
3. pwm_positive = port:PA05<3><0><default><default>

Copy code

Would really appreaciate any help.
Thanks.
