Edit1:
Seems this is a problem with bluetooth in general. I found the following article from the steam forums about bluetooth headset problems in GTA V. It might be worth a read to shed light on any problems your having.
Edit 2:
If you start Battlefield 4 on windows 10 and havnt disabled “handsfree telephony as below” all your sound will cut out.

There’s a problem with Battlefield 4 and Battlefield 1 where you get no sound if your playing with a bluetooth headset. After a bit of googling and research i found the solution;
1. Goto; control panel->Hardware and Sound->Devices and Printers
Battlefield Sound Effects (91) Most recent Oldest Shortest duration Longest duration Any Length 2 sec 2 sec - 5 sec 5 sec - 20 sec 20 sec - 1 min 1 min All libraries Mike Dred SFX Bible BLASTWAVE FX Rob Bridgett Richard Humphries Fusehive Lynne Publishing Audiophile Sound and Music. No sound in battlefield 4. I've been having this issue that whenever I launch battlefield 4 I'm getting no sound at all. I've tried various solutions such as turning off origin sound notifications, setting my default audio device. Pretty much all of the above that I've found on the internet.
2. Select Properties on your Bluetooth headset and go to the services section.
3. Uncheck “Handsfree Telephony”.
Note this works on Windows 10 cant say if it work on Windows 7 or 8.
Hello, people sorry If my grammar is off but... I AM EXTREMELY HAPPY!!!Battlefield 4 No Sound Windows 10 Fix
SO! Guess what, I have every single Battlefield 4 sound. Well, not every. Just the main things. Let me list.Here it is
Bullet_Craft
Character
Destruction
Explosives
FX
GameSounds
Maoism
Music
Objects
UI
Vehicles
Weapons.
Each weapon has over 4 different reload sounds, over 10 shooting sounds, and more!!! OVER 40 ITEMS INCLUDING DEFIBS AND C4!!!!
I have recently started modding and this will be the absolute most useful thing in OpenSpades modding. With hundreds of sounds with bullet flybys, rocket flybys, building destruction and much much more. I will soon release this file. Remeber! You cannot find this in the battlefield 4 files, its encrypted into them and are hidden. I am extremely happy I found this file.
