hello,
i'm a new node-red user maybe it is not so complicated for others but i can't find a solution.
i have mpd running, now i want to play a message(not with mpd) over this soundcard but the message is not so loud.
that means before i can play the message i must look if mpd state is "play or stop" and read the original volume.
now i can set the new volume to "75%" play the message and after that set original volume + if its played before set mpd state to play.
how can i solve this?
