(Solved) Need help with random crashes with XAudio2_7.dll

[LeanLatin]

I need help with random crashes on new saves. The crashes occur 5-15 minutes randomly, whether i’m jumping, walking, or just standing still. This issue only started in saves with 3-4 hours of progress, while my previous 100-hour save had no XAudio2_7.dll-related crashes.

 

What I’ve Tried:

• Disable realtek driver
• Installed DirectX again  
• Reinstall XAudio2_7.dll

• Unpack sound folder from BSA mods ( unlikely since i doesn't install any new mods and my previous playthrough was 100hours with no crashes realted to Xaudio) 

 

My suspicious is the mods Death Consume All. At 3-4 hours into a new save, i arrived in Falkreath, and the random crashes after 5-15min of plays began here, though it worked fine in my last playthrough.

The second is Auri, i often visit Auri’s house after reaching Falkreath. Initially CTD after 2-3sec standing in her house , but loading a save from just before her house lets me enter without crashing. After that, random crashes still occur elsewhere. This mod was also stable in my last playthrough.

I’ve already started two new games, and both had the same result. I think it’s related to my audio driver or software, however i've tried many solutions without success.

Start by switching to a competent crash logger.

I already have it, here you go

The crash occured because the code hit an int3 instruction which is a breakpoint. With no debugger attached, I believe it falls back to terminating the application.

 

The error was: "SimpList: non-growable list ran out of room for new elements"

The list that overflowed can have a maximum of 64 elements.

 

Back with more info in a bit once I get my tools to download the symbols...

 

Edit: The callstack in xaudio2_7.dll looked like this:

XAudio2_7.dll+0x002B72C is in CPointerList<>::AddTail(...) XAudio2_7.dll+0x002ADF3 is in XAUDIO2::CX2SourceVoice::SubmitSourceBuffer(...)

 

So... would it be safe to assume that the issue is that you have too many sound sources? Maybe the max number of channels is 64, and the game tried to play more than 64 sounds at once? Something along these lines is the vibe I'm getting here. May want to Google this information. XAudio is a common library, I doubt you're the only one seeing this.

That would indicate that my guess about the sound channels overflowing was correct then. The issue is not limited to Immersive Weapon Switch however - simply playing too many sounds at once would do it.

This happened to me with the mod "Immersive Sounds Compendium" ages ago. Don't know if it still does, I've been avoiding that mod since then. ..Even if it sounds great..
