So I noticed recently that my tablet will emit a low electronic hum whenever there is audio being played on the tablet . This happens with any audio being played on the tablet (independent of audio file or player) at all volumes and when the volume is completely muted, however it is most noticeable when at low volumes and when muted since there is no sound to overpower the hum. I was wondering if anyone else can see if this is something with all Nexus 7 2013 models or mine needs to be repaired by asus. This is quite annoying when trying to watch videos at low volumes. I purchased this day of launch if that matters at all. Thanks in advanced for the help.
