Anyone has that?
When I play game for some reason the music that is supposed to play in a gunfights just isn't there but after a save/load or randomly sometimes it's plays as normal. Music is also missed from many scenes and has the same problem.
I'm on Windows 8.1.

Sorry for being late to the party.. Win10 here,, I too found not 100% of the sound working for me (gun sounds / fx was missing). Turns out that playing the games sound through my monitor (using the monitors hdmi cable) "swallowed" these fx sounds. Switching the sound output in Win to additional headphones instead of monitor speakers solved the problem for me.

Same issue with my win 10 laptop..
Searching for compatibility problems reported that GoG Galaxy uses win 8
compatibility mode..
I changed exe compatibility to tha,but
same issues..
Putting in-game audio options to"Direct audio"kind of fixed problem..
The beginning misses audio but,title screen and game has it with hdmi on..
