[Trigger] 3D Sounds

[Unelith]

I have imported my MP3 sound and wanted it to play after using a skill, but it just doesn't work. I can play it as normal sound but then it is global, and i want it to apply only to specific area. I have used:

• Sound - Play VrykulRoar <gen> at 100.00% volume attached to (Triggering unit)

Other actions in this triger work, so it's not problem with events or conditions.
These are my sonud variable settings:
- 3d sound checked

Left column:
- 127
- 10
- 10
- 1.0

Right:
- 600
- 10000
- 3000

I don't know how these are called in English, i have Polish version of the editor.
I also tried default settings but this didn't help.
