Meta sound parameter not updating in real time

This is the setup. Once you create a Volume input, play the sound, then while playing adjust the Volume, it changes the gain accordingly.
Then you stop the sound, play again and adjust, it doesn’t do anything until I restart the editor, or if I create a brand new input. I remember this happening since around 5.4, and has happened to me with 2 different windows machines and a macbook. Haven’t found any info around…
