headphones and speakers sound only works after resuming from sleep

[KGCybeX]

good day all

this is my first bug report, please be nice

I have had this problem with Linux Mint 14 , Linux Mint 15 and now with Ubuntu Gnome 15.04, Ubuntu Gnome 15.10 again.

May I add, I recently got my USB headset while using Ubuntu 15.04 so the USB headset is not the problem

COLD BOOT

What happens: on cold boot, headphones and speakers occasionally work, USB headphones always work when plugged in or when hotplugged. Trying to unmute, adjust sound volume etc on headphones or speakers is pointless, nothing seems to make a sound

In sound adapters, all adapters are listed, adapter switches between speakers and headphones as expect, inshort sound adapter/s work exactly as expected/required BUT just no sound.

RESUME

When I resume from sleep, sound magically works (headphones and speakers) (and USB works like normal), I am not sure what other information is required, but I gave what I thought is relevant.

lspci -v | grep Audio

apologies, I don't think I am able to say with certainty which package it affects, what I can mention is ALSA is somewhere in the mix ,could someone be more specific to how to track which package the problem lies in, but pertaining to my "driver" issue, thnx

this occured when ANY sound setting was default (except volume was different, ofc)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Induane (oldspiceap)]

I can confirm this bug & more interestingly, I have exactly the same sound device: Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)

I can see no issues with it working, things *feel* like they are working. When I plug in a headphone jack, the device is switched. Pauvcontrol even shows audio coming through it in levels. There simply isn't any actual audio from the jack.
