Although I do it using ESL it may be helpful for your case. When issuing the broadcast request I create a 'correlation ID' variable with a generated unique ID (can be any suitable string) for each file to be broadcast. The ID is passed back to the ESL app after each particular file stops playing back.

Hi All,

I am dealing with a little problem...

To play asynchronous audio in my Lua script I use the api function
"uuid_broadcast {uuid} {fileName} aleg". This all works well and audio
is being buffered if I call my function multiple times.
When I want to abort all plays and flush the buffer I use "uuid_break
{uuid} all". This all works excellent!

My problem is I at certain points need to know if audio is being
played (or awaits in the buffer) and need to pause execution untill
all audio is beging played (or flushed).

Is there a way of doing this in either Lua or apiFunctions? or a
channel variable perhaps? I have looked and tryed but cannot seem to
find a way doing this.

Any hints (or solution ;-) appreciated!

Regards,
Michael Lutz
