Bug in audio controls?

F32 mAudioTypeVolume[Audio::NumAudioTypes];

ConsoleFunction(alxGetChannelVolume, S32, 2, 2, "alxGetChannelVolume(channel_id)")
{
   U32 type = dAtoi(argv[1]);
   if(type >= Audio::NumAudioTypes)
   {
      Con::errorf(ConsoleLogEntry::General, "alxGetChannelVolume: invalid channel '%d'", dAtoi(argv[1]));
      return(0.f);
   }

   return(mAudioTypeVolume[type]);
}

F32 volume = mClampF(dAtof(argv[2]), 0.f, 1.f);
//...
   mAudioTypeVolume[type] = volume;
