Audio doesn't work in BF4 PC

Can you give us a bit more information so we can try and help you more like did it work then poof gone.

First things I would look at is in game sound settings and desktop sound settings. If this is ok then check for new driver for your sound card or motherboard sound and even check event viewer for errors in sound.

It still doesn't work but thanks for everything, I'll wait until the next update to see if it works. Thank you!

Dang we should be able to find you a fix :/ How about we test your windows for errors as it cant hurt. And this was how I got my BF4 issues fixed as my windows seemed good to go until I was in BF4 then it was issue city. Try this as it cant hurt and I would like to see you be able to play BF4 issue free and it can be done. I dont mind helping you at all so no worries on this :]

Test your windows for errors
This works in all windows O/S vista win 7,8 and 8.1 windows system file checker :]

...... sfc /scannow ..... ever hear of it if not your going to love this .... it will inspect all the important windows files as well as the windows DLL files. If windows system file checker finds any issues with the windows files and windows DLL files it will replace them. This little tool as well as the event viewer saved me and fully helped me fix my BF4 issues as well as saved my .... many a format since I found it. This is the best toy they ever put in windows :]

1 - Open administrator command prompt and close web pages and programs like origin.

2 - Type or copy and paste in sfc /scannow and hit enter, This takes 5 min to 15 min SSD vs HD

3 - This can go one of a few ways ..... no errors ... it fixed some errors ..... could not fix all errors...... does not finish checking and errors out ....... and the last one could not fix errors at all :/

4 -After its done reboot and do it again even if you had no errors the first time or had errors, could not fix ... run sfc /scannow again and when its done a second time reboot. You need to do this a and get no errors 2 x in a row ...

5- So if you ran it 2x and no errors your safe you can stop now for now lol, If you had errors first time but not the second then run sfc /scannow again and when its done reboot. You need to get could not find any errors 2 x to be safe. If it still finds errors try and run it a few more times until it finds no errors 2x AND ALWAYS REBOOT BETWEEN RUNNING sfc /scannow

6 - If you get a message indicating that it can not be repaired and you ran sfc /scannow more then 3x in a row on win vista or 7 mm you need a format or try repair win 7 :/ But after format or repair and all updates are done run sfc /scannow to make sure your windows is stable same deal 2x error free reboot between, then If your O/S is Win8 or Win 8,1 then you can run this next command / line in administrator command prompt. Sadly this does not work for win vista or 7 :/ It will restore the health of your PC and you dont lose anything

dism.exe /online /cleanup-image /restorehealth ------- ONLY works for windows 8 and 8.1

7 - When its done reboot
