This issue is something I had for a while and I had no idea what went wrong. Finally, after closely examining it, I figured it out.
THIS ISSUE WON'T HAPPEN TO EVERYONE. HOWEVER, IF YOU'RE THE RARE PERSON WHO GETS IT, HERE IS A SOLUTION. THIS IS ALSO FOR ME INCASE I FORGET IN THE FUTURE
There is a solution to sounds that I have figured out while thinking about what Skye said in his FAQ section. Incase anyone out there is having issues with sounds of certain firearms not working in your maps, first do the following:
Download ALL Weapon Common Assets that Skye has included and Re-Link on launcher.
Now this was something he mentioned in his FAQ's but make sure to do that. This also fixes textures.
If your weapons still don't have sound,
Check your launcher for an error that has this filename:
Code Snippet
Plaintext
ERROR /_t9_elemental_pop.csv missing
The code will be very similar to this.
Now, I have no idea what this code is for. For me personally, it is useless and so I decided to remove it.
Before removing it, I searched through my entire HDD to see if a file like this exists but it doesn't. (If you have a different code and it says it cant find the sound, simply try to add the missing sound to Black Ops III/share/raw/sound/aliases or remove the line of code entirely if the sound isn't even necessary for your map or you are not able to locate it anywhere)
Find your zm_mapname/sound/zoneconfig/zm_mapname.SZC
After removing it, re-link your map in the launcher and Build.
Should fix the sound issues.
Ofcourse, this fix should only be tried if you already have done everything mentioned in the FAQ's. This fix is also pretty specific but NO ONE has mentioned this before so I am leaving this here.
