So I have successfully been using KDE Neon 4.5 and 4.6 for the last few months. I have a simplified BIOS (SeaBIOS) working and I can do almost anything on my Chromebook. A few issues I have are as follows:

1. No Sound. I think it is an issue with an integrated HDMI soundcard. I'm not sure because I haven't found any information on the web about it yet.
2. I cannot upgrade from the 4.4.0-22 Linux kernel release. If I do, I cannot use KDE at all. It won't even load into the Neon DE.

Those are the 2 main issues I'm having. Could someone maybe point me in the right direction of where to solve these issues? My priority is #2 since it inhibits me from upgrading to the new features of KDE. I'm not sure what information the community needs to help me, but please let me know.

Thank you all!

Hi,

first question as with all hardware related stuff: relevant output of lspci -k

The kernel question, however, bugs me. As I don't know Neon and its underlying structure I am not much help on that front...

your Kernel "should" update automatically (and everything else that is upgradeable) if you run

Code: Select all

sudo apt-get update && sudo apt-get dist-upgrade

in a terminal .

at present I am on kernel 4.4.0-31-generic

check

Code: Select all

pactl list sources

and see if the sound card is recognized by the system.

it may not be set to the correct channel and profile in "system settings>Multimedia"

I fined "pavucontrol" (pulse audio volume control)easier to use myself ,,,,,,,,,,,,

Code: Select all

sudo apt install pavucontrol

I will try this. I will have to post my output when I get home, but when I used Ubuntu, I know that with the latest kernel nothing worked, which tells me something is being left out of the kernel image that was previously included. Now with KDE neon, I'm having the same issue and have to stay on -22 kernel or the GUI won't even load.

But I will post the output for my hardware when I get home today.

Pavucontrol didn't change anything. I believe there is something wrong with the driver. I fear that there won't be any way to fix this.

Unfortunately I haven't got time to do it myself. Perhaps the Arch Wiki has something on it as well.
