Apparently I've just got the exact same bug, with the same machine (M3800).
My kernel currently is 3.16.0-43. The bug also shows up with 3.16.0-41.
It makes the headphones absolutely unusable.
The white noise sound pops up when the sound card is woken up, and it
disappears (or more precisely
Hallo.
I have the exact same noise problem on headphones
on brand-new HP Zbook 15 G2.

Mario's workaround worked fine for me! It will be nice if it does get
fixed upstream.

I tried this workaround and it fixed the problem. Still it have to be
fixed in the kernel.

I have tested 3.16.0-30-generic and it did not work for me. Still same
background noise.

Based on posts at that community forum, it sounds like this should be
fixed in 3.16. Affected users can try to install linux-generic-lts-
utopic on 14.04 to see if it resolves the issue.

Can someone please validate that 3.16 does fix it though? If not, there
are some other workarounds mentioned:
hda-verb /dev/snd/hwC1D0 0x0c SET_AMP_GAIN_MUTE 0x5180
hda-verb /dev/snd/hwC1D0 0x0c SET_AMP_GAIN_MUTE 0x6180

Raymond, thanks for the pointer! If I understand correctly, I would have
to compile the kernel myself with the suggested patch, right? If so,
please bear with me for a few days, I've been working round the clock
