Issue description

There are the following problems with web export:

• For a sound that has been played at least once, the playing variable is always true
• It is impossible to set the volume of audio channels, even Master
• Cannot add effects to channels (they are ignored)

Steps to reproduce

• Add an AudioStreamPlayer node to the scene
• Add WAV sound to it
• Play sound
• Check the $node.playing variable for the sound, it will be true even when the sound stops playing.

Minimal reproduction project (MRP)

Bugsquad edit: added the MRP

• Cannot add effects to channels (they are ignored)

For this, this is as designed for the moment. There will maybe be a way to implement basic effects, but custom ones are out of the question. If you need badly effects, you'll need to use streams instead.

#94269 may fix some of these issues.

Reopening as #94268 had a typo that prevented the fix to work.

#94800 should fix the issue.
