Hissing/whirring sound from the ear piece when you write or prepare to write.

[Windows Central Question]

Hi,

I don't know if this is related to 950 or W10M in general, but there is as hissing sound when I mark the box in order to start write e.g. in WhatsApp or in EDGE. In Whatsapp the sound sometimes remains on even after you have closed the app. I think it could be source of a battery draining or at least unnecessary waist of energy. The sound does not change if you adjust the volume and it remains on when you mute the phone. Does anyone else have this?

I've seen this happen on my PC. And I still haven't figured out whether there was a problem with the speaker or something else
