The game plays amazing for me on a i7 2600k with 16 gig ddr3 corsair ram, OCZ Vertex 4 256gb ssd, and a AMD Radeon 6950 2GB Sapphire flex card (which is below specs game is calling for) on max settings. The surround sound doesn't seem to work properly which i am trying to resolve. My PC streams full Dolby 5.1 for everything but this game. Only in Battlefield. Battlefield 4 is the genre-defining action blockbuster made from moments that blur the line between game and glory. Fueled by the next-generation power and fidelity of Frostbite 3, Battlefield 4 provides a visceral, dramatic experience unlike any other. Only in Battlefield can you demolish the buildings shielding your enemy. Lately i have the issue that i have no sound at all in BF 4 on the PC. Not on the loading screen or in game. (no gun sounds, vehicles or running or talking.) i reinstalled the game, repaired the game, checked the sound options (they're all correct) en even switched them around. Some people say t. I've had an issue where I permanently have no sound. I've done a repair install and more and alas I still have no sound. The Official Battlefield 4 Subreddit.

I have not tried uninstalling and reinstalling, and I would like to avoid that if possible. I have gone into my OS playback and nothing worked.

I don't have speakers so I don't really know. I think I have an HDMI. And yes I am in game right now and I checked the settings and I made sure to hit save.
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
2. Select Properties on your Bluetooth headset and go to the services section.
3. Uncheck “Handsfree Telephony”.
