Sound Entity Doesn't work

[batass]

Thank you for your response. I changed the .snt file.

It's now:

<SOUNDENTITY>
<SOUNDS>
<Main>
<Sound File="ambience_haunting.ogg" />
</Main>
</SOUNDS>
<PROPERTIES Volume="0.5" MinDistance="0" MaxDistance="0" Random="1" Interval="0" FadeEnd="False" FadeStart="False" Stream="True" Loop="True" Use3D="False" Blockable="False" BlockVolumeMul="0.5" Priority="0" />
</SOUNDENTITY>

But unfortunately, there is still the same issue. I can't here the sound.
Is there anything I forget?

Thanks.
