Hi there,

Probably one of those old bugs however, I've tried basically all methods except for formatting my pc which I really wish not to.
Below are the list of things I tried.

1. setting cpu core manually to maximum, checking all other launcher params
2. sfc/scannow
3. Direct X SDK install, Direct X install / repair
4. Microsoft Visual C++ Redistributable Clean Install
5. Changing Audio Devices and checking Spatial Sound on/off Enhance features On/Off (I have Wireless Headset, Wired Speakers directly connected to speaker)
6. Manually adding x3daudio1_7.dll file to the game directory both x86 and x64
7. Re Install of Arma 3
8. Deleting Arma 3 Folder in Documents folder
9. Re Installing graphics / audio driver
10. Installing sound Mod JSRS

Of course all other programs emits sound just fine.
Indeed this is a new machine built however am not sure what is causing this issue.
I've tried debugging using process monitor myself but nothing seems to be related except for x3daudio1_7.dll which I've already tried.

I'd really appreciate any suggestions for fixing this issue as my life is becoming dull and painful without Arma.. ToT
