GPIO Sound on Pi Zero W
« on: April 16, 2019, 10:34:16 PM »
I know this topic has been discussed, but I'm wondering if I only use pin 18 for pixels can I route audio through PIN 19? And if so, how do I get that to show up as my audio output device and settings?

No, the pixel output library uses both of the PWM outputs for the two pixel outputs.  The library doesn't currently allow disabling one of the outputs, they are both enabled even if you only have pixels connected to one.

Thanks. I was worried that was the case, but thought I'd ask. USB time I suppose.
