I recently purchased HP Envy 700-327C.
Out of the box, I noticed a constant static / white noise whenever I plug a headphone into the audio out jack from the headphone. It is the same noise from the front or rear jack. It is very noticeable when no sound is playing. I have tried multiple headphones and speakers with the same problem. When I mute the sound, the noise stops. If I increase the volume, the noise level doesn't change. I have disabled the mic and also reinstalled the driver. I even tried to use the generic windows sound driver. I have an older HP desktop at home before and an HP at work and never had this issue. Is there anything else I can do?
