audioplugin_phonon.dll access violation 4.0.3
Unity, both in editor and standalone can often crash when the SteamAudioSource performs its Awake phase. I've been having this issue for a while now, but I've found no fixes for this as of yet. This can happen any time, like when an audio source is dynamically created but also when a new scene is loaded.
I've compiled the audioplugin_phonon.dll from source so I could get the exact location where the exception occurred with the pbd files, and it always seems to come from the method iplSourceRetain(IPLSource source)

Here the dump, log and pbd files: crash.zip
My knowledge of C++ is unfortunately very limited, but it seems to have something to do with this implementation:
case SIMULATION_OUTPUTS_PTR_LOW:
#if defined(IPL_CPU_X86) || defined(IPL_CPU_ARMV7)
setSource(state, reinterpret_cast<IPLSource>(*reinterpret_cast<uint32_t*>(&value)));
#else
effect->simulationSourceTemp = static_cast<uint64_t>(*reinterpret_cast<uint32_t*>(&value));
#endif
break;
case SIMULATION_OUTPUTS_PTR_HIGH:
#if defined(IPL_CPU_X64) || defined(IPL_CPU_ARMV8)
effect->simulationSourceTemp = (static_cast<uint64_t>(*reinterpret_cast<uint32_t*>(&value)) << 32) | effect->simulationSourceTemp;
setSource(state, reinterpret_cast<IPLSource>(effect->simulationSourceTemp));
#endif
And then specifically the SIMULATION_OUTPUTS_PTR_HIGH case. I exclusively build for 64-bit. The iplSourceRetain method retrieves an IPLSource with address pointer of 0x0000013a7f7fffff. I have 0 clue if that's a valid address.
@stepperman - Thanks for reporting. We tried to repro this issue but with no success. Any of the following will help towards a repro:
- Are you able to share a standalone project we can use for repro?
- What does your Steam Audio Source component looks like?
- When does typically the crash happen? Creating an Audio Source with Steam Audio Source component on it? Switching scenes?
we've got the same issue with 4.0.3 - it happens on scene load initialization
@achandak reproducing this issue is extremely hard, it happens at complete random moments and can happen when the scene initialises (like @glemeshko-bsg mentioned) or when a new steam audio source is created. Audio Sources in my project always have a Steam Audio Source attached with the Spatialize checkbox on. The settings of the Steam Audio Source also seem to have no effect on reducing this crash.
I'll create a project that abuses loading scenes and creating a lot of audio sources to try and repro this issue. I'll upload that soon.
Update: I couldn't figure out a repro unfortunately. I've tried making something that continuously switches scene and creates audio sources but it creates too much memory (without freeing) them to properly test that for a long time.
I moved most of the initialization from Awake to Start in SteamAudioSource.cs. I'm not sure if it works - but the crashes seem to have disappeared. I still get the occasional editor crash, but that's to be expected of Unity 😝.
My Start() and Awake() methods look like this now.
private void Awake()
{
mSimulator = SteamAudioManager.Simulator;
var settings = SteamAudioManager.GetSimulationSettings(false);
mSource = new Source(SteamAudioManager.Simulator, settings);
mAudioEngineSource = AudioEngineSource.Create(SteamAudioSettings.Singleton.audioEngine);
if (mAudioEngineSource != null)
{
mAudioEngineSource.Initialize(gameObject);
}
}
private void Start()
{
if (mAudioEngineSource != null)
{
mAudioEngineSource.UpdateParameters(this);
}
mAudioSource = GetComponent<AudioSource>();
mThis = GCHandle.Alloc(this);
if (SteamAudioSettings.Singleton.audioEngine == AudioEngineType.Unity &&
distanceAttenuation &&
distanceAttenuationInput == DistanceAttenuationInput.CurveDriven &&
reflections &&
useDistanceCurveForReflections)
{
mAttenuationData.rolloffMode = mAudioSource.rolloffMode;
mAttenuationData.minDistance = mAudioSource.minDistance;
mAttenuationData.maxDistance = mAudioSource.maxDistance;
mAttenuationData.curve = mAudioSource.GetCustomCurve(AudioSourceCurveType.CustomRolloff);
mCurveAttenuationModel.type = DistanceAttenuationModelType.Callback;
mCurveAttenuationModel.callback = EvaluateDistanceCurve;
mCurveAttenuationModel.userData = GCHandle.ToIntPtr(mThis);
mCurveAttenuationModel.dirty = Bool.False;
}
}
Oh, and because OnDestroy might be called when the object never activates, I changed the OnDestroy() method to this:
private void OnDestroy()
{
if (mAudioEngineSource != null)
{
mAudioEngineSource.Destroy();
}
if(mThis.IsAllocated) mThis.Free();
}
I'm not sure if this is anything to go by for fixing this issue - if not, this issue can be closed.
So I want to post an update: ever since applying the changes above I've had 0 crashes. I suspect there being something wrong with the order of execution in the native library somewhere.
Unfortunately, the suggested fix listed here doesn't prevent crashes for us.
Is there some order of initialization that must be enforced to prevent this crash? It'd be nice for a developer to let us know so we can implement checks to ensure the initialization order is correct.
I think this is potentially the same issue as I had here: https://github.com/ValveSoftware/steam-audio/issues/190
It seemed to work for me once I set the IPL_SIMULATIONFLAGS_REFLECTIONS flag, but I'm not familiar with how the Unity stuff is set up.
To this day I've had 0 crashes when applying this fix, only a few rare ones in the editor. Whereas before it crashed about 30% of the time both in standalone and editor.
I tried reverting my changes and the crashes came back immediately so I'm kind of disappointed to hear this doesn't fix the issue!
I thought initially it had to do something with the audio thread trying to access data that doesn't yet exist (or something) though that doesn't really make sense. Alas I don't know enough about the code to make a real educated guess, though I deed peep around a little and saw nothing out of the ordinary.
I also found it impossible to replicate in a small project, for some reason it only happens in the bigger ones?? idk
We've just released Steam Audio 4.1.0, which includes various crash fixes: https://github.com/ValveSoftware/steam-audio/releases/tag/v4.1.0.
Try it out and let us know if these crashes persist in the new version.
