Audio bug fix that's worked for me so far.
Ok so I like a lot of people have been having the sound drop out for days now and I think I may have it sussed if this works for you like it does for me please return here and comment.
-1st off launch STAR WARS BATTLEFRONT and minimize it.
Open the windows START tab bottom left and type " taskmgr.exe " in the search field then right click it and pin to task bar (for future easier access).
-Right click the new Task manager icon on your task bar and run it as administrator.
-go to the processes tab at the top and find battlefront in the list.
- right click the battlefront process and click the priority button and set it to " above normal".
Bare in mind I asked you to add task manager to your task bar because you will have to do this every time you wan't to play with audio.
good luck hope this works for you too.
