-nosound startup parameter - no crash.

another one test.
firing handgun - no crash. firing spmg - game crash.

Confirmed.
Bug first appeared on 21 JAN 2016 and is still present in Dev Branch version 1.55.134043

Can you both (nikita320106 & mr_book.PXS.Cpl) please post some reproduction steps?

I was not able to reproduce the issue after several tries with random gear.

Just place some units in editor (2D or 3D) and hit "play scenario", then shot several times (game crash after one or several shots). I check opfor grenadier and rifleman.

virtual arsenal. trying mx rifle -crash; spmg -crash; trg(tavor) -crash; m20 rifle -crash; dlc markshmen rifle(d'nt remember correctly)-crash; connected silencer to any of - no crash; handgun weapon - no crash.
sound card - sound blaster x-fi or high definition audio on-board - 100% same result. changing audio driver or sound parameters on driver, or sound source count in game parameters(32-128), nor disabling /enabling sound card - same result. only -nosound startup parameter allow to continue w/o crash.

@Koala: Nikita's description is so damn accurate, I can barely add anything to it.
Maybe this: the game also crashes when a frag grenade explodes.
I tried it in the editor, in Virtual Reality, on Altis and Stratis.
The sound card I use is a M-Audio Revolution 5.1. Fumbling around with sound settings didn't help.

That is strange.

I took my time and tested every available weapon in the latest development branch without any crashes.

As far as I can see in the crashdumps your arma3.exe is causing some troubles.

You guys should verify the integrity of your game cache (with Steam) and try again. Maybe some corrupt files are messing with the new audio enhancement.

Please tell me if that helped.

Already done this (verify the integrity), nothing happen, the problem remains.

Strange thing, when i try play with addons, rhs ak-74 done several shots without problem, but when i go in third person and rotate camera to barrel of the gun (I had to hear the crack sound) made the shot, then game crash

P.S. Sorry for bad english

makkuranin, can you please upload your crashdump (rtp-file) here too?

But before you do make sure no mod is activated and, after the game crashed, look for the latest rtp-file.

Add yesterday ArmaReport_Log to "Attached Files"
(ArmaReport_Log_20160122T153138_XXXX.zip) This is what needed?

Alright then try following solution. Simply delete your Arma3.exe and again re-verify the integrity of the game cache (re-download of the exe-file with Steam)

According to the both attached rpt-files, the arma3.exe seems to cause troubles.

I hope it works for you.

@Koala: bad news here. Verifying files didn't do anything. Also deleting and re-downloading arma3.exe or the Addons-, dll- or dta-folder didn't help.
I even completely re-installed Arma 3, it still keeps crashing.
Crash report is up.

No. didn't help. Still crash.

Same issue here (Didn't see duplicate..).
Uploaded dumpfile as ArmaReport_Log_20160122T142436.zip

I got the same issue.Firing pistols, submachine guns,guns with a silencer or throwing smoke grenades won't crash it,HE grenades or unsilenced guns will.-nosound parameter "fixes" the crashing, but playing without sound can't be the final solution.validating the files via steam and replacing the arma3.exe by deleting it and the validate via steam did not fix it.Uploaded dumpfile as ArmaReport_C_Brennigan.zip.

Same problem, uploaded zip file "ArmaReport_Log_20160124T125256_Omistaja.zip".

Hey guys. I will get in contact with one of the developers tomorrow and maybe he will find the cause (and a solution) of the trouble you all have.

Here is a list of things you can also try for yourself. Maybe one of these steps might help:

• Update the graphics card drivers to a newer version.
• Rollback the graphics card drivers to an older version.
• Check the temperature of your GPUs and CPUs.
• Re-install DirectX.
• Uninstall the Visual C++ 2013 Redistributable package (x86 version), restart your computer and install the package again (do not use the Repair function).
• Run a Windows System File Check tool to repair corrupted system files.

Hello,

thank you all for your feedback. This issue should be resolved in one of the upcoming Steam Dev updates (and of course not present in the next Stable).

Should you experience this problem again after next update, please let us know.

Thank you

Seems to be completely fixed with the newest update :D

No crash after 26/01/2016 update. Thank you.

Hi guys, please tell us if the issues are gone or if some of you still have problems with the development branch?

Yes Sir,
works fine! Thank you very much.

Thank you all for the feedback and cooperation :)
