Issue description:
Playing a sound with a audiostreamplayer or a audiostreamplayer2D instance on a audio bus (cascacde) with enabled equalizer effect will lead to a high cpu load and frame timeouts after the sound play was finished. On larger godot project this results in a delay up to 10.000 msec or more where you also have load from GPU usage or gdscript usage. I have tested this behavior on Linux and on Windows with a small sample project.
Same behavior here too. In one of my sample project run (under Windows) the delay was just 22ms over a longer period but it shows the issue as well.
Disabling the equalizer (EQ21) effect in each audio bus by gdscript is solving the cpu usage problem immediately.
Steps to reproduce:
Place a audiostreamplayer in a node2d
Add audio busses and EQ21 effect like in the picture below:
Set audiostreamplayer instance in the inspector to Bus "EQ2"
Start the godot editor debugger tab "Profile" and hit start.
Enable sub Master Eq21 and other audio bus effect for the measure
Play a short sample sound and look what happens after sound play has finished.
