I BELIEVE I'VE FOUND IT. When checking that the pin assignments were correct, I noticed that GPIO 2 & 3 were assigned to I2C (https://www.raspberrypi.org/documentation/usage/gpio/). I have no idea what that is, but I remembered when digging through config.txt last night that there was a line: dtparam=i2c_arm=on,spi=on,i2s=on I simply turned i2c_arm to off, and now the switch works as expected for the whole time that the machine is powered on. Hooray! So: what is i2c used for? Is it DAC related? Just for my own knowledge - I am not outputting any audio from this Pi, as it's only used as a 'Now Playing' display. 2x squeezebox classics | 2x squeezebox booms | 2x squeezebox receivers | 1x raspberry pi 2 b w/ picoreplayer, 7\" touch screen (iqaudio dac+ now deprecated in favour of receiver) | orangesqueeze as android controller lms v7.9.2 running as a docker in unraid on a hp microserver gen8 ------------------------------------------------------------------------ JadeMonkee's Profile: http://forums.slimdevices.com/member.php?userid=20481 View this thread: http://forums.slimdevices.com/showthread.php?t=109404 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
