Sound Volume is Low

Hi All I am using TGE Where i have to play the audio file. I am playing audio using this code

new AudioProfile(AudioIntroMusicProfile)
{
filename = "~/data/sound/Sound.wav";
description = "AudioGui";
preload = true;
};


function Test22()
{
$AudioTestHandleA = alxCreateSource("AudioIntroMusicProfile", expandFilename("~data/sound/Hall.wav"));

alxPlay($AudioTestHandleA);

}


The Sound is playing. But the sound voice is very less. compare to Media Player or any other player.

The sound i hearing from TGE while running is very less.

I have increased the sound volume to highest level but the sound is very less in TGE.

i have also changed this flag in pref.cs

pref::Audio::channelVolume1 = 1;
$pref::Audio::channelVolume2 = 1;

but the sound is very less.

could any one help me how to increase the sound volume in TGE.


Thanks and Regards
John Peter
