play sound: what input to set to get notification on empty queue?

[Ponyoonthecliff]

No problem with 'always' mode - it works fine everytime.

But 'on empty queue' works properly (i. e. playing sound on finishing queue) never or extremely rare. How make it work right?

Connect Vae decode output for example, works 100% of the time for me. (it will play once ur generation is done = queue is empty)
