How to stop the IKEA Eneby from going to sleep while on AUX

for a raspberry pi, or debian-based device connected by 3.5mm jack.

tested on dietpi distro running on Rpi B gen 1 with shairplay-sync

Download quiet low tone file, rename to 15tone.wav

From the root user home folder (~/ when logged in to root)

wget https://s.put.re/w8s9Lk5A.wav -O /root/15tone.wav

Create script to detect audio-playback, and if not play silent tone

nano playsoundifnotplaying.sh

copy paste the follow script:

#!/bin/bash
if grep -q RUNNING /proc/asound/card*/*p/*/status 2>&1; then
   echo "Audio playing, not doing anything"
else
   echo "No audio playing, playing silent tone"
   aplay /root/15tone.wav
fi

ctrl:x to save and exit

then make the script executable:

chmod +x ./playsoundifnotplaying.sh

you can test the script by running ./playsoundifnotplaying.sh

Add to following to crontab, for the script to run every 15 minutes (Eneby sleep time is 20min):

open crontab

crontab -e

add the line:

*/15 * * * * /bin/bash /root/playsoundifnotplaying.sh >/dev/null 2>&1

ctrl:x to save and exit

You might hear a quiet "pop" every 15 minutes or so when no audio is otherwise playing.
