Sony: Fix coming for Xperia KitKat audio bug

Since Sony's Xperia Z1, Z1 Compact and Z Ultra started receiving their Android 4.4 KitKat updates a couple of weeks back, some Xperia owners have been reporting audio glitches on their devices. Specifically, a troublesome bug would sometimes cause notifications and calls to be played through the internal speaker rather than the external speaker, making them almost impossible to hear. But there's good news for those affected this morning, as Sony says a fix is on the way.
