I am trying to find a way to pause Moode Audio while playing music so that an announcement can be played over the speakers with a aplay. I have looked at the API Rest commands here:

https://github.com/moode-player/moode/blob/develop/www/setup.txt

However, there does not seem to be a pause, stop and start. Accordingly, I have used the REST command below to successfully lower Moode Audio’s volume in hopes that I then can play an announcement file with aplay for example aplay WeWillBeClosingSoon.wav and then restore Moode Audio’s volume. However, the lowering of the volume seems to equally affect aplay. Does anyone know how this can be achieved?

curl "http://192.168.40.252/command/?cmd=set_volume -dn 35"

aplay WeWillBeClosingSoon.wav

curl "http://192.168.40.252/command/?cmd=set_volume -up 35"

I believe this may be possible with volumio but I was hoping to stick with Moode.
