Notebook Audio

Hi, I bought a new HP spectre x360,

For my job I need to run simulation trought OpenFOAM, so it's easyer for me to use Linux.  Nearly everything work out of the box, except one things... sound.  I post a bug on launchpad, here the link:

Bug Hp spectre x360

It as nearly everything you need to debug the phenomena. I know that you don't officially suport linux on that computer, but it would be fun to be at least linux compatible.

Thing I know:

There was a bug that really look like this one on the Dell XPS 13. The bug was in the bios, wich was setting the sound card to alternative mode that was not working. I think is the same here. I need to find a way to tell the bios to load everything like if it is windows 8.1 (Yeah, I just ask no special treatement!) 

Thank you,

I will give all support you need. I really wish to correct this bug.

PS: (HP if you correct this bug you will sell three more of those computer, they all want one in the lab!)

Follow up:

It's seem that we are now hable to use the lagacy mode from the sound card. It's good, but not perfect. The fix for the i2c will come soon, the latest kernel code ask about a mysterious drivers file that doesn't exist right now in the linux firmware directories. So, this case is close because the issue as been addressed. Follow the launchpad bug for furter improvement.

**SOLUTION MAY NOT BE THE SAME FOR YOUR DISTRIBUTION**

From Spano:

If you use gummiboot you should have something like that:

options acpi_osi="!Windows 2013" acpi_osi="!Windows 2012" acpi_backlight=vendor root=/dev/sda2 rw

The selected solution under this post is for Debian based distribution. I will put the solution for other distribution on this post, if they are on the forum. (You don't find it? Adjust the solution to fit your distribution and post-it, you will make people happy 🙂  )
