CODO maps have duplicated sounds in game

[skeetwarez]

What are you trying to do?
Trying to update and port CODO maps to fix visual and crashing issues and build into 276 zones. (maybe one day PR into client)

What problem are you having?
Every CODO map including the ones bundled with the client have duplicated sounds that stack on top of each other in game that cause audio issues, ie sounding metallic

Please walk us through the steps you have taken when you encountered this problem.
Any CODO map from the old zones bundled with IW4x, new ones that are zone 461, and ones that are dumped with zonebuilder and converted to zone version 276 have duplicated in game sounds.

What have you tried so far?
ive tried deleting the ents and changing sound flags since CODO maps use different sound flags that arent mapped the same and so far, nothing has worked. Even just adding just one of the problematic sounds that are in the map causes it. Weapon sounds, announcers, and voices are unaffected.

What version of IW4x are you using?
R4911

Anything else we should know?
You should check the initial code for how CODO zones are read since the issue is probably in there.

** Some commands I used in game to troubleshoot are the following:
snd_draw3D 1-3 (this will show you visually where the sound is placed in game)
snd_drawInfo 1-3 (this will show a list in the middle of your screen)
g_entinfo 1
g_entinfo_maxdist (i set this to 1000)

when doing g_entinfo 1 with 1000 dist, every sound has a "ET_SCRIPTMOVER" which doesn't happen in neither IW4 native maps nor ones ported from IW3 or IW5

the duplicated sound also shares the same entity number as the "ET_SCRIPTMOVER"
