Via Polygon:

DICE rolled out another update patch for Battlefield 4 on Xbox 360 today and said they are looking into a crashing issue with Windows PC version, according toBattlelog.

"We are working on a fix for an issue on PC that causes the game to freeze, resulting in a sound loop," reads a banner at the top of the site. "We will share more information once available."

It seems to me like every patch causes more problems, a one step forward, two steps back sort of thing.
