I was wondering if it was possible to programmatically detect if there is something connected to the analog audio output jack. I know it's possible on some other hardware but not sure about on the Raspberry Pi.
So far this can be done with some easy soldering, would this affect the audio quality?Burngate wrote: So to do this successfully, D12 & D13 would have to be removed, and be replaced with, say 1k resistors. Pin 3 or 4 (not both) is then wired to a GPIO, with a 10k pull-up. There would have to be a low-pass filter to remove the audio, and a diode pair to protect the GPIO.
In theory, no. But I haven't actually done it, so I can't be absolute.vicary wrote:So far this can be done with some easy soldering, would this affect the audio quality?
