How to use SoundRequestFeedback to tell if a sound is being played or not?

I am trying to reference the .playing function in SoundRequestFeedback.h(link to file) to allow my system to finish speaking before executing the rest of the code but I can't seem to figure out how to properly do that.

In my header file I declared sound_play::SoundRequestFeedback_<ContainerAllocator> v and proceeded to try and do

ROS_INFO("%d", v.playing); // prints False<->0 
sound_play::SoundClient.say("This is a test message"); //Says "This is a test message"
while(v.playing){}
    //stays in a loop while the system is saying the message
ROS_INFO("%d", v.playing); // also prints False, but does so while the system is still saying the message.

so v.playing always returns 0 and I don't know why. Does anyone know why ?

Could you link to the files that you are referring to?

I don't think this is possible as the sound_play::Soundclient only publishes requests but does not listen for any feedback. I also don't understand your code. How is your feedback-object linked to the Soundclient? Does this piece of code even compile? (and btw: .playing is not a function)

You could run the soundplay_node in sound_play. This nodes offers an SoundRequest-ActionServer to which you can send your goal and wait for the result. In my experiements, the result-message came around 2 seconds after the sound really finished, but you could check that with your setup.

Hi, the piece of code compiled and it always returned 0. Could you provide the code example from your experiments ? I looked at the tutorials on ros.wiki but I'm not quite sure how to apply it to my case
