Comment 11 for bug 1598571

Hi, I found a FIX.
My laptop is an ASUS X555UB but the fix applies to severals X555 laptops.

So, I spent all night searching and I found that this is an actual bug with an actual patch.
Unfortunately the patch will be queued for Linux v4.12 as written in this message:
http://www.spinics.net/lists/alsa-devel/msg60448.html

You will need to compile the kernel by yourself, I used v4.6.3 from Ubuntu PPA:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.3-yakkety/

Apply the Ubuntu patches.

Now apply all 5 patches from:

http://www.spinics.net/lists/alsa-devel/msg60443.html
http://www.spinics.net/lists/alsa-devel/msg60444.html
http://www.spinics.net/lists/alsa-devel/msg60445.html
http://www.spinics.net/lists/alsa-devel/msg60446.html
http://www.spinics.net/lists/alsa-devel/msg60447.html

Now, If I remember correctly the patch 2 and 4 gives some problems, you will have to add the code lines manually to /sound/pci/hda/patch_realtek.c

Compile the result into .deb

PS: I did not include the details, you will need to search by yourself how to download from source, apply patches and make a .deb package.

Hope that helped.
Good Luck!
