Cannot load the kernel

[srikantpatnaik]

Hello, nice documentation. Sorry, I have no other means to contact you, hence this issue. I have tried to replicate your findings but failed, is it possible for you to upload your kernel/initrd deb files? I'm desperate to see audio working. Thanks. You may email me at srikant@fossee.in, and remove this discussion.

Hello, thank you!

I'm completing this documentation as I advance with my device.

I've not been able to enable sound successfully yet, I only get some crackles but no working sound.

Audio device is not being listed with lspci.

Updating to kernel 4.4 and latest intel sound firmware may help.

I will update "asound.state" file and kernel ".config" as soon as possible.

I guess we will get a working sound soon.

I also tried various settings, but none worked. I'm following this page closely http://ubuntuforums.org/showthread.php?t=2254322&page=53.

Thank you, I have been following that forum too ;)

Some ASUS laptops/tablets has the same ASoC audio chipset and load the same modules but this machines can show the audio hardware with lspci :?

I could check modules loaded in one of those asus laptops and they are the same that we can see loaded in a flexx10 device:

I guess it's not working because something is wrong with firmware files or I have not found the good ones, I'm using the latest downloaded from git.

I have built a new kernel and tried some new options to define ALSA values.

I have updated repo with:

- New kernel .config for latest git version 4.4.0-rc8+.
- New asound.state 
- An script to configure ALSA values.
- More files ;)

I got more crackles at boot and login time now, I can see the audio device in alsamixer and gnome to change values but still no sound at all. ;(

I'm closing this issue because kernel is loading with many distributions.
