Battlefront Sound Effects

i have this problem too. I dont hear any type of sound if-game, only the music and the effects of the menu, but nothing about shoots and effects.

Happens to me too after loading a new match. The sound will either crackle or the effects for the fighter and for the computer talking to you will not play. 

I'm having this too, this is game breaking for me not only because i want to hear the awesomely recorded starwars sounds, but because i have to constantly restart my game every 15-20 mins to get the sounds to work. i was also getting a crackling but i think that was a driver issue after updating several of my drivers it seems the crackling have gone away. Alot of others are having this issue as well it mosly seems to be affecting AMD cpu chipsets butr there is the odd intel cpu in there as well.

BF forums page with users reporting issue: http://starwars.ea.com/starwars/battlefront/forums/discussion/8271/audio-issues

Im running

 ASrock extreme 9 990fx MB (15.7.1 chipset) (1.7 bios)

 FX 9590 CPU

 AMD Sapphire R9 390x 8GB GPU (15.11.1 driver)

 16 GB gkill sniper 2133 ram

There seem to be three modes for audio:

1. All audio except UI "beeps" and the occasional environmental effect are missing, and
2. sound is crakling horribly as if amplified into clipping, or
3. sound works.

Both can only be fixed by restarting the game and hoping for the best, chances for each seem to be the same.

(edit) The crackling apparently sometimes goes away when a match starts or ends.

Update graphics the the new AMD Radeon Software Crimson Edition Display Driver version 15.30.1025. This has solved my issues, it is not a problem with bettlefront or origin or ea, this is a driver issue. Has been 3 days no issues
