I have a similar problem. PC No Sound FX, Tried Multiple "Fixes"
I'll report it anyway. I very rarely have any sound at all in matches. Occasionally I have music. but that's it. no lazer blasts, no footsteps, no breathing/ running sounds. I hear a ship once in a while.
Main Menu works fine and has sounds
My specs are the following if it helps:
CPU: Intel Core i7 4770K processor (No Overclocking)
Motherboard: Asus Gryphon Z97 Bios updated
GPU: Intel HD Graphics 4600 ( run the game up to Med without a problem and beta ran fine with this GPU) (Intel(R) Graphics Accelerator Driver Beta 15.40.12.4326 for Windows 10 64bit)
Sound Card Onboard: Realtek® ALC892 8-Channel High Definition Audio (Driver V6.0.1.7661 for Windows 10 64bit)
Hard Disk: 2TB WD Black x2
RAM: Gskill DDR3 4x4 (16GB) 1600Mhz Sniper (PC3 12800)
O.S.: Windows 10 Pro - 64bit
"Drivers are updated "
Had no sound error while playing the beta, just wanted to point it out
"Possible fix"
Go to Control Panel > Sound.
Select your device and choose Properties. Check the enhancements tab and disable any enhancements that are active.
Then go to the Advanced tab and set the quality to "16 bit, 44100 Hz (CD Quality)"
I do this and the sound effects problem continues on during multiplayer game
And no word from Dice or EA about them fixing it
