I recently bought an Ascend 520 and I've had issues with the audio output. There is often a low crackling/static noise when playing music, but it varies: it's least bad with Pandora, slightly worse with YouTube, and worse still with Google Play Music (whether downloaded or streamed). It also seems worse through Bluetooth headphones.
I've Googled this issue and read a number of threads, and it seems like it's a very common issue with KitKat, with no consensus on any fix. I've tried a bunch of the ideas suggested without success. However, a lot of the threads are around a year old, so I'm hoping something concrete has arisen since then. (I would prefer not to root my phone if possible) .
