Sound helper is invalid.

Error message

Sound helper is invalid.

What it means

Thrown by SoundManager.SetSoundHelper when the soundHelper argument is null. The sound helper is mandatory for SoundManager operation (later code such as AddSoundAgentHelper explicitly requires it), so setting a null helper is rejected.

Solutions

1. Attach/create a valid ISoundHelper implementation and pass it
2. Check that GetComponent<SoundHelper>() did not return null before calling
3. Verify initialization order: helper creation precedes SetSoundHelper

Example fix

// before
m_SoundManager.SetSoundHelper(GetComponent<SoundHelper>()); // may be null
// after
var helper = GetComponent<SoundHelper>();
if (helper != null) { m_SoundManager.SetSoundHelper(helper); }

if (soundHelper == null) throw new InvalidOperationException("SoundHelper missing");
soundManager.SetSoundHelper(soundHelper);

bool HasSoundHelper(ISoundHelper h) => h != null;

try { soundManager.SetSoundHelper(soundHelper); }
catch (GameFrameworkException ex) { Log.Error(ex.Message); }

When it happens

Trigger: Calling soundManager.SetSoundHelper(null); passing a helper reference from a component that failed to resolve.

Common situations: Missing SoundHelper script attached to the game object; typos in GetComponent calls; scene setup omissions.
