Audio Nodes Driven By Value does not work

[enzyme69]

I have this setup of pre-recorded animation (box animated ups and downs) and supposedly the position of the Cube should be driving the value of Math node inside Audio Nodes and trigger sound, but even with value changing in the node view, the sound does not seem to trigger.

If I am using Animation Nodes and Expression node, it sort of working and the sound sink is triggered. But since I have multiple sink, very often I get too much noise, is there anyway to Mix all the sounds so they are not all becoming too loud?
