**SoundChannel null issue**  
In my code I frequently call a volume adjusting function where I assign new volumes to all soundchannels in use with a simple command.  
The error I encounter comes when I call this function before all soundChannels have been initiated with an actual sound.

The critical part of my code is this:

```auto

var themetransform:SoundTransform = new SoundTransform(setVol);
  if (SC_B != null); {       

       SC_B.soundTransform = themetransform; // Causes Error
   }                              
   

```

I get an error saying “can’t access null object” or similar – and this follows after my check if the SC\_B is null.  
This issue only arises early in the execution of my project, that is before SC\_B has been assigned to a sound\_B.play() instance.  
Is there any other way than comparing to null as above that I can use to prevent this error?

```
  Please advice,
