Airplay status commandline

[neophyte]

I'm using a Rpi3 with HifiBerry DAC+

I have a relay, that turns on and off my amplifier, connected to GPIO pin.
I have a script running in the background that takes care of turning off and on the amplifier, whit this line:
mpc status | grep playing > /dev/null

However, when I use airplay, the music player daemon is not used, and therefore the amp is turned off by the script.
Is there a similar command line interface to the airplay like the one above for mpc?
So it would something like this:
if [ mpc status | grep playing > /dev/null ] || [ airplay status | grep active ]; then
#set GPIO high

Hi neophyte,

i would use

Code: Select all

cat /proc/asound/card*/pcm*/sub*/status | grep state:

because this will work with all playback sources (mpd, airplay, UPnP and Spotify).

Hi neophyte and Frank

Will anyone of you share the script to control a relay?

How about this [Addon] RuneUI GPIO for power on / off audio equipments.
