AudioLowPassFilter.cutoffFrequency does not work

So I'm trying to change the lowpassfilter cutoff frequency this way:

Code (csharp):

1.  
2.         AudioLowPassFilter filter = GetComponent<AudioLowPassFilter>();
3.         filter.cutoffFrequency = 1000f;
4.  

I'm getting this error:

Only custom filters can be played. Please add a custom filter or an audioclip to the audiosource (GameObject).

When I try to change the cutoff frequency of the highpass filter, it seems to work fine:

Code (csharp):

1.  
2.         AudioHighPassFilter filter = GetComponent<AudioHighPassFilter>();
3.         filter.cutoffFrequency = 1000f;
4.  

I've searched on google and couldn't find many topics about this, I found http://forum.unity3d.com/threads/131908-Low-Pass-filter-problems but no solution. Anyone an idea how to fix this or is this hopeless?

Do you have UnityPro?

 

Ehm yeah because If I didn't how would I be able to make the high pass filter work?

 

I figured out that it actually does work, but the value of the cutoff frequency never changes in the inspector so there definitely is some weird bug.

Problem solved, thread can be closed now.

 

Same behaviour here. Thanks for the headsup. I don´t see it in the editor, nor do i hear any changes when changing this value per script, rather annoying. A fix would be nice.

 

How did you solve the problem?

Edit: Sorry I misread.

It does work, but the inspector isn't updating.

 

It does not work for Unity 5.
It doesnt change in the inspector nor in-game.
Only if I slide the value in the inspector at runtime.

My code is very simple, just a bool check that alternates between setting the cutoff to 500 or 5000.
The filter is never affected, i tried Mathf.Lerp first but then resorted to trying simpler things.

Annoying and unnecassary.

 

It doesn't work for me. Changing cutoff frequency runtime by script only works in editor but not in builds
