Asus x555u Audio issues

[Juan_Fiorenzano]

Hello community how are you doing? I have this problem with my laptop's audio. The system recognize the hardware but simply doesn't emit any sound I raised the volume to the max but nothing happens, I upgrade my kernel to 4.4.8 due to the systems doesn't recognized that my earphones was plugged, now my laptop is completely mute. This is the output of lspci which concern with my audio device.

00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
    Subsystem: ASUSTeK Computer Inc. Sunrise Point-LP HD Audio
    Flags: bus master, fast devsel, latency 32, IRQ 16
    Memory at df328000 (64-bit, non-prefetchable) [size=16K]
    Memory at df300000 (64-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: snd_hda_intel

If you see in the command output, in Capabilities section said <access denied> I don't know if this has something to do.

Have you yet tried to install pulseaudio volume control and checking the configuration settings to make sure the right device is being used?
The package you want will be "pavucontrol"

I've already installed pulseaudio know it recognized when I plug my earphone but still soundless, in the device section say Built-in Audio

Look under the Configuration Tab at the top...mine shows this <Screenshot>
We are taking this slowly at first to eliminate what is causing this.

This is my configuration tab

Ok that's what I wanted to see..and looks good.
Now we need to check that the driver is installed properly.

sudo apt-get install linux-restricted-modules-`uname -r` linux-generic

After installing the modules, you will need to reboot for the changes to take effect.

If the modules are already installed, proceed to the next step to check to see whether your hardware is recognizing the sound card as installed.

Is the sound card physically installed and recognized by your hardware?

Open a terminal and type

lspci -v | grep -A7 -i "audio"

Paste the output of the above back here using code tags.

When I type this:

sudo apt-get install linux-restricted-modules-`uname -r` linux-generic

the output are these errors messages

Well that makes for messy diagnosis solution.
Lets see what options we have to boot from.
Post back the return of this in the terminal:

dpkg -l | grep linux-image | grep ii

This will return only properly-installed packages with that name
