Answers I've gotten:
1.) Kindly follow the steps below:
Ensure Origin is fully closed by clicking the Origin Menu and selecting Exit.
Delete the following folders:
Origin folder - Found in C:\ProgramData\
Origin folder - Found in C:\Users\%USERNAME%\AppData\Local\
Origin folder - Found in C:\Users\%USERNAME%\AppData\Roaming\
Note: These folders are hidden by default, and you will need to un-hide to be able to locate them. To unhide the folders, please follow the steps on this link: http://windows.microsoft.com/en-ie/windows/show-hidden-files#show-hidden-files=windows-7
Then after that, relaunch the Origin app then let me know if the sounds on the game is okay now.
(This did not work for me)
2.)i see, on Origin client. Select "Application Settings" from the Origin menu, in the "General" tab, scroll to the bottom and find the "Origin Beta Participation" section. Select the "Update to the beta version if available" check box. Proceed to uninstall Origin app from Control Panel of your pc, then run ccleaner by following the steps on this link:http://help.ea.com/en/article/how-to-use-ccleaner-to-fix-pc-issues/ , then reinstall Origin app from https://www.origin.com/en-gb/download . Once you have downloaded the Origin app, go the game, right-click on the game and click ‘Check for Update’. Also right-click on the game and click ‘Repair game"

3.)Have you tried to disable the antivirus and firewall then try the game again?
(This also did not work for me....for obvious reasons)
4.) Thank you for staying connected I**. I'm sorry for the wait. Our support team asked this -- Have the customer go to load and load their last saved game and see if it is just good old fashion corruption in the game.

Then I saw this message pop up There may be a problem communicating with G**** . Please wait while your chat is transferred to another EA Advisor
*sigh*
5.) I understand, what I mean to say is if you tried a new game on DAI, new character just to check if there will be an audio issue.
(Audio issue persisted)
6.) Thanks for patiently waiting, our specialist are asking if you tried to perform clean boot on your PC to make sure there is nothing interfering?
(This di not work)
7.) Could you disable it (Origin in game) and try the game again. Let's see if it will work.
(This did not work)
These are all of the steps they have to fix this issue, since they could not help me they escalated my case. I'm waiting to hear from the specialist team via email.
