I couldn't find it, but it would be very nice if runeaudio could be controlled by IR (infra red) remote control. If already possible, please can you tell me how? If not possible yet, then I would like to suggest it as new feature.
depending on the hardware you are using it should be easy to setup an IR remote. The ODROID images have built-in IR functionality. On the latest images for Raspberry Pi 2/3 all needed packages are preinstalled. There are many useful threads on the forum.
The easiest way to do it would be to use a USB remote, see here.
