Some DSP Settings fail to load

[Fortune117]

Describe the bug

When setting up mixers I noticed that they would stop loading correctly. and instead print this in console.

2025/01/07 20:38:31.3101	[engine/Developer] DSP: Warning, failed to allocate delay line.	
2025/01/07 20:38:31.3101	[engine/Developer] DSP: Warning, failed to allocate delay for reverb.	

To Reproduce

1. Open the bug repo
2. Change the dsp effect of 2-3 of the mixers (you may have to do it a couple times)
3. Save the mixer
4. See errors in console

In order to get the bug to happen on a new project:

1. create two extra child mixers
2. add a dsp effect to each and one dsp effect to the game mixer
3. change the dsp effect
4. save the mixer
5. see errors in console

Expected behavior

Dsp effects should load correctly.

Fixed

There's a very similar issue that's caused by starting the game multiple times, at least in the editor. Should I make a new issue for that?

It's likely fixed by this fix, but what is it?
