Ive recently purchased a xp13 (of the newer generation with 7th generation processors) and have been experiencing constant audio issues.

The first is the static noise emitted from the laptop, it seems to mostly happen when either the speakers or headphones are in use but does not emit from either, and persists if you play music with out any sound enabled (so the track is playing but without producing any sound- works with videos too). I have not found a strait solution for this on the forums yet, just lots of 'are you sure its the laptop' stuff. (yes, btw i am sure). This problem is regularly intermittent, not occurring all the time but fairly frequently. 

 The second is the awful sound quality the laptop kicks out. it sounds like a load of light static over all music. This i managed to fix to a certain extent by reinstalling the audio drivers form realtech. This seemingly disabled the Maxxaudio app (no window popped up on inserting headphones) and made the headphones sound as they should. All was well until the Maxxaudio app reappeared without me enabling or installing it and it brought the bad quality audio with it. Is there a way of permanently uninstalling/ disabling this or a way of preventing it from automatically coming back?

Ive also had problem with the laptop infrequently producing a loud whining / static sound through the headphones or speakers. It sounds very similar to the sound produced when a guitar amp is plugged in wrong. It seems to be more frequent after reinstalling the new drivers.
