Need help changing sound on ion engine

[INSULINt]

There is a REALLY old mod that used to change the ion engine sound, but basically replaced the original cfg for the part, which has changed a bit since the mod. Want to do it via MM, but can't seem to get anything to work. I've taken the sound files from the original and placed them in IonEngineSounds/Sounds folder and have a cfg in IonEngineSounds to try to add the audio to the engine.

I've tried:

@PART[ionEngine]
{
	@AUDIO[*]
	{
		@clip = IonEngineSounds/Sounds/sound_loop
	}
}

@PART[ionEngine]
{
		IonEngineSounds/Sounds/sound_loop = running
}

@PART[ionEngine]
{
	@EFFECTS
	{
		@AUDIO
		{
			@IonPlume
			{
				@clip = IonEngineSounds/Sounds/sound_loop
			}
		}
	}
}

Among other things. Even tried with ionplume and audio reversed.

Hope someone can help. Spent the last 3 hours googling everything I could think of and perusing through a bunch of MM threads to no avail, so?

Managed to get it to work! Putting this here in case someone wants to rework the original mod using those sound files:

@PART[ionEngine]:final
{
	@EFFECTS
	{
		running_custom
		{
			AUDIO
			{
				channel = Ship
				clip = path/to/sound_loop
				volume = 0.0 0.0
				volume = 1.0 1.1
				pitch = 0.0 0.2
				pitch = 1.0 0.9
				loop = true
			}
		}
		flameout
		{
			AUDIO
			{
				channel = Ship
				clip = path/to/sound_stop
				volume = 1.0
				pitch = 2.0
				loop = false
			}
		}
	}

	@MODULE[ModuleEnginesFX]
	{
		runningEffectName = running_custom
	}
}
