Unity 5.3 crash in xaudio

Question

Hi,

We get a crash in Unity on 5.3; it's only started after we integrated WWise.  Log below:

Unity Editor [version: Unity 5.3.0f4_2524e04062b4]

XAudio2_7.dll caused a Breakpoint (0x80000003)

I'm experiencing the same problem, roughly every other attempt to run the game:

Unity Editor [version: Unity 5.3.1f1_cc9cbbcc37b4]

XAudio2_7.dll caused a Breakpoint (0x80000003)
  in module XAudio2_7.dll at 0033:0b72b72c.

I don't know who is to blame for that - Wwise or Unity?

---

I'm also getting this crash - is there any more information available on this problem? I'm inclined to blame Unity 5.3, since it has other stability problems and I wasn't getting this crash in Unity 5.2.

Unity Editor [version: Unity 5.3.1f1_cc9cbbcc37b4]

XAudio2_7.dll caused a Breakpoint (0x80000003)
  in module XAudio2_7.dll at 0033:6254b72c.

Also, I found XAudio2_7.pdb, so here's the stack trace:
XAudio2_7.dll!CPointerList<void,1,64,0>::AddTail(void *)    Unknown
XAudio2_7.dll!XAUDIO2::CX2SourceVoice::SubmitSourceBuffer(struct XAUDIO2_BUFFER const *,struct XAUDIO2_BUFFER_WMA const *)    Unknown
AkSoundEngine.dll!00007ff95533a608()    Unknown
[External Code]

This appears to happen just after print this: "SimpList: non-growable list ran out of room for new elements"

---

You can safely remove XAudio2_7.dll from System32 and be happy with getting rid of this crash (other Unity 5.3 crashes will still be there).

Answer 1

Hi,

I was able to reproduce this crash by doing the following in the Unity editor:

1. Press "Play" in the editor
2. Press "Pause"
3. Press "Play" to stop the game
4. Press "Play" again. The editor will crash.

We will have a fix for that in the next version (2015.1.5). We do not recommend deleting the XAudio dll from your system32 folder, as it might interfere with other programs.

 

While waiting for a fix, a workaroud is possible. In AkInitializer.cs, add the following lines right after initSettings.uDefaultPoolSize = (uint)defaultPoolSize * 1024;

#if UNITY_STANDALONE_WIN
        initSettings.eMainOutputType = AkAudioAPI.AkAPI_Wasapi;
#endif

Thank you for the update and for providing a workaround! I've integrated it and will let you know if I get the crash again. Can you give an ETA for 2015.1.15?

---

Unfortunately I'm still getting the same crash sometimes, even with the workaround. Is there any new information on this bug or the new version?

---

This crash might be unrelated. Can you post the crash log when it happens? Thanks!

---

I just got the crash again recently, here's the log (it looks identical to last time unfortunately):

Unity Editor [version: Unity 5.3.1f1_cc9cbbcc37b4]

xaudio2_7.dll caused a Breakpoint (0x80000003)
  in module xaudio2_7.dll at 0033:fcfab72c.

And here's the stack trace from the minidump with the XAudio2.7 pdb from the June 2010 DirectX SDK:

xaudio2_7.dll!CPointerList<void,1,64,0>::AddTail(void *)    Unknown
xaudio2_7.dll!XAUDIO2::CX2SourceVoice::SubmitSourceBuffer(struct XAUDIO2_BUFFER const *,struct XAUDIO2_BUFFER_WMA const *)    Unknown
AkSoundEngine.dll!00007ff8e672a608()    Unknown


This is with the patch that you mentioned earlier. It happens much less frequently, so that's good at least! And I've just upgraded to Unity 5.3.2 and haven't noticed the crash yet, but I'll let you know if I do.

---

We are seeing this same crash with Unity 5.4.0f3. We are still using Wwise 2015.1.2 IIRC because it is what the TBE 3Dception dudes ship with. When I try your work around above it seems fine locally on my windows box. However, when our OSX system on travis-ci.com tries to build there are compile errors (despite telling unity we are -buildTarget win64). Any ideas or suggestions?

Assets/Wwise/Deployment/Components/AkInitializer.cs(106,51): error CS0117: `AkAudioAPI' does not contain a definition for `AkAPI_Wasapi'
