i am having this same problem too
have done snd_restart
have done cache verification and have also done snd_rebuildaudiocache, not to mention a whole heap of uninstalling and reinstalling.
console says it was unable to load sound, and that it cannott create mixer.

Yes, i don't have a solution yet

i have been looking as well, but no luck on my end.

When did your problem start?

yesterday. was working fine before, not is stuffed.
have tried to change sound mixers, now says "unable to load" and that the sound is not in the disk reposotory

I am having the same issue. It was working yesterday, but not today.

resolved it.
in common folder (insurgency game folder) run the core .exe as admin.

WHat do you mean with "the core" what file is that? Forgive me being noobish here. I have same problem, doesnt work even thou i´ve unsub, reinstalled, sub. Same problem.

i dont have sound for moste guns either and i cant find a "core.exe" so not resolved

( and if you mean the insurgency.exe, running that in administrator doesnt solve the problem either)

EDIT:

unsubscribing and re-subscribing did not work however manualy deleting the mod and than cache verification fixed it. i have gun sound again.

1. the map were day of infamy is located is called: 601757902
(it is located at: steamapps\workshop\content\222880\601757902 and not in the same place as Insurgency the game is)

2. Delete everything in it

3. now you will have to verify the integrity of the game cache (make sure you are still subscribed to this mod)

4. after the verification a download should start with a size of ~200 MB

5. After the download is complete re-start Insurgency

hope this helped for others too

I Started the game as administrator and it worked. The solutions may vary between users

ive noticed alot of these problems start from sounds mods. That atleast what ive noticed

So it seems

programs/steam/steamapps/common/insurgency2

the.exe file called insurgency.exe ithe one i am talking about.
starting it as admin fixed it for me.

MIN3, many thanks for this. Worked like a charm when nothing else did. Thanks a bunch!
