Whooops :-) I think it is BCM26 & BCM16 - but weirdly these are not connected to the amp (there aren't even solder-points!). I'll try other ones and see if the crackling is gone! https://de.pinout.xyz/pinout/io_pi_zero (Layout from which I counted the GPIO's) In fact the button does not power down, I used them to command the player to toggle PLAY/PAUSE. And the button is only in the mA range with its current consumption. ------------------------------------------------------------------------ maeffjus's Profile: http://forums.slimdevices.com/member.php?userid=68549 View this thread: http://forums.slimdevices.com/showthread.php?t=109769 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
