Re: No dialogue sound

It is possible you are seeing some game file corruption. 

Click Manage button and then Repair to detect and hopefully fix this.

Additional PC steps:

Download and install all available Windows Updates
Run System File Checker to ensure the integrity of your Windows System files: http://support.microsoft.com/kb/929833
Perform a clean boot before starting the game: http://support.microsoft.com/kb/929135 or http://help.ea.com/en/article/how-to-clean-boot-your-pc/

Thanks.
