I've found that since updating my Lumia 950 with the Windows 10 Mobile anniversary update that the overall sound quality of my device has been negatively effected.
There seems to be some sort of "background feed" (sounds like white noise) that emits from the speakers before, during and after a sound plays. For example, the sound when you lock and unlock your screen now does not sound as sharp and clear as it used to be, and after the sound plays, you can hear this white noise play for a few seconds afterwards.
I noticed this after playing some music or pausing, this background feed would play for about 5 seconds after the music stops and then cuts off.
Is anyone else getting this?
