flex 2-14 speaker noise, driver problem ?

2015-03-26, 2:16 AM

hi all,

recently bought flex-2 14 then noticed that the speaker is making noise like hisss, or static noise,

that happen when playing sound, even when the speaker is set to mute or plugging in a headphone,

after the sound had played, the noise gone. the noise came back again when playing another sound,

the noise can be heard clearly when the speakers in line/ parallel with the ears,

 

what really bothers me is when I mute the speaker/ plug a headphone, the noise is there,

already tried newest driver from realtek, but no luck.

No proper fix. Workaround is to uninstall the Realtek driver and use the generic Windows driver.
