Hi All,

The second time MasterAudio.PlaySoundAtVolume is called, it returns null.
There is only one sound per group. No variations.

Can you suggest ways to debug this?

	public void playSound() {

		_frogPlayResults = MasterAudio.PlaySoundAtVolume( _variationName, // string sType,
			                                                          1.0f, // float volumePercentage,
			                                                          Vector3.zero, // Vector3 sourcePosition,
			                                                          null, // float? pitch = null,
			                                                		  frogTransform, // Transform sourceTrans = null,
			                                                          null, // string variationName = null,
			                                                          true, // bool attachToSource = false,
			                                                          0.0f, // float delaySoundTime = 0f,
			                                                          false, // bool useVector3 = false,
			                                                          true, // bool makePlaySoundResult = false,
			                                                          false, // bool isChaining = false,
			                                                          false, // bool isSingleSubscribedPlay = false,
			                                                          false ); // bool triggeredAsChildGroup = false) {

		_frogPlayResults.ActingVariation.SoundFinished += soundIsOver;
	}

	void soundIsOver() {

		StartCoroutine( "restartSound" );

	}

	IEnumerator restartSound() {

		_frogPlayResults.ActingVariation.SoundFinished -= soundIsOver;
		
		yield return new WaitForSeconds( randomSleep.Next( 3, 10 ) );

		playSound();

	}

You should not be directly calling PlaySoundAtVolume. It is private I believe so you cannot. Are you doing that?

You should instead be calling playSoundX methods which later call that method after many checks.

We hacked the private to make it public.
There is no API that returns a PlaySoundResult and has bool attachToSource parameter.
That is a separate issue.

We changed to a MasterAudio.PlaySound3DAtTransform.
After setting breakpoints,
IT's jumping out without reaching the return.
wait for this to stop playing or play further. playedPercenage:23.7741 retriggerPercent:50

Have no idea what this means.
Why would SoundFinished throw event unless it is finished playing?

Thanks

The API you want wraps PlaySound and is this:


        var result = MasterAudio.PlaySound3DFollowTransform("Arrow", this.transform);

Yes, it returns a PlaySoundResult and is on the API website.

About the "wait for this to stop playing": You have all available voices of that Sound Group playing already. Using the Retrigger Percentage, an already playing voice can be "stolen" to play a new sound only if its clip position is past the percentage specified (defaults to 50%). The code is exiting because yours is only at 23% so it can't be stolen.

If you need more voices, increase the Voices / weight field in your individual Variations in the Sound Group. That defaults to 1 for each Variation and means that only 1 of that Variation can be played at a time. If you want to be able to play 5, change it to 5.

SoundFinished probably fired after this when the clip *was done playing*.
