Hello, as the title says, the game is completely muted, I searched the net for solutions but It seems I dont find a solution working for me.
Any advice?
Im using win7x64 with a 16gb / i7-3770 Intel, i have no issues with my pc atm.

Have you updated your audio drivers to the latest version? Possibly from manufacturer website of the actual audio chip and not from manufacturer site of a motherboard (if you're using onboard one, because motherboard manufacturers rarely update their drivers, but actual manufacturer does, usually it's Realtek).

I've found that my Nahimic audio program was causing this issue, so if your computer has that or a simlar program try shutting it down.

*update

Sound issues are back again.

Have same problem. Sound worked initially, then got messed up during the game, and ever since I'm not getting any sound in game. No restarts help.
Tried reinstalling audio driver, tried using headphones. No dice.

I have figured out a solution for my case. Apparently Unity engine is not really compatible with most sound-enhancing software, such as Asus Sonic Studio which came prebundled with my laptop. After I uninstalled it and restarted my computer, sound was fixed. I've seen reports of other sound-enhancing software causing problem, don't remember the name, unfortunately, so you might try checking what you have running.

Same. Sound worked perfectly for me until tonight, and now its very off and distant sounding

edit:
nvm, working again
