I start think the noise coming from the speaker on N9 is related to wifi since this happen often when send/receive data from internet?

Can someone confirm this? Maybe the wifi can configured/tweaked to get rid of this behave, tweaking with dB settings or something?

Btw... Can someone tell if this issue exists in nemo also?

I am guessing know and have now clue where to start but if someone can point me right direction I am willing to play with it..

As said already I have f.... up harmattan anyway so would be nice get stuff working with sailfish on n9.
