Hi Maximilian,
I biult a nice „squeezebox touch“-like device with your great max2play! Thank you so much – it was very easy 😉
As I added a rotary encoder with a push-button-switch build in to my IQaudIO Pi-AMP+ the requestet feature would be very helpful for me too.
It would be nice to choose the function of the button/s. For me the following functionality seems to be good:
– short press: mute (or stop playback) and maybe shut down the attached 7 inch RPi Touchscreen (like a standby function so you don’t have to wait for booting up the device) –> short press again: unmute (or start playback) and power on the touchscreen
– long press: shutdown the RPi
I found some code but that’s my first linux experience and I have no programming skills 🙁

For testing I connected the switch with the IQaudIO Pi-AMP+ „mute“ pin. It works – but only as long as I keep the button pressed. Do you know if this behaviour could be changed or is it realized „in hardware“ of the IQaudIO Pi-AMP+? As an alternative I could use the other left GPIO 25 (which is reserved for the IR receiver)!?
