I have installed the latest version of ubuntu (Ubuntu 18.04.1 LTS - kernel 4.15.0-43-generic) on my pc Cherry Trail - Intel Atomx5 Z8350.
But the sound card is not recognized.
After reading some forums it seems that sound card driver is not present on my setup.
Under windows the sound card works with Intel SST Audio Device drivers while it should match the CX2072X drive-codec for linux.
I have seen the link which shows the codec driver compilation on 4.18 kernel version.
https://github.com/conexant/codec_drivers/commit/4d9cfc5188c6c2709b1d7533a363ff485294c1e3
But I do not know how to install them in my ubuntu and also do I need to install the kernel version 4.18 before these for the compatibility issue.
Sorry I am not much familiar with Linux so any kind of help would be appreciated.

My external monitor, connected via HDMI was working fine but now is not being detected (it says 'No video input'). I'm pretty sure I didn't make any changes to make it stop - it was working on the same setup yesterday.
I'm a pretty new linux user and also don't know much about graphics hardware and drivers. Appreciate any help, I'd like to understand what's going on!
I'm running Ubuntu 16.04.3 kernel 4.10.0-33
lshw -c video gives:
*-display

physical id: 2
bus info: pci#0000:00:02.0

I've tried booting from grub into kernel 4.8.0 and the monitor still wasn't detected.
I've also tried to no avail:
sudo apt-get update
sudo apt-get install --reinstall xserver-xorg-video-intel xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
I've also tried running the Intel graphics update tool and this also hasn't solved anything.
EDIT: It seems like I get the 'No video input' probelm if I plug in the HDMI cord before the computer has finished booting.
Pretty much the only answer one can give here based on the available information is, try checking the display cables, and, if that doesn't help, file a bug. Debugging display problems like this can be fairly involved, with several cycles of requesting and providing more information. That doesn't really work all that well here.
The alternatives for filing the bug are Ubuntu Launchpad and drm/i915 upstream. Upstream has the best knowledge about the driver and the hardware, but, depending on the issue, you might be expected to build and run the userspace components or the kernel from upstream git repositories.
I come across the problem and solve it with exactly the same card (i had same lshw -c video) by searching the NVIDIA X-Server settings (search inside apps) on my Ubuntu 16 LTS and activate the NVIDIA drivers for this card (I have a NVIDIA GEFORCE GTX)
After i log out and i have a bad errors display and i was blocked " this computer is running in low display mode" .
I just switch off the computer and restart it...and taatatatat HDMI was working and was able to display on my external Sansumg 27''
I had the exact same issue as OP. lshw not showing HDMI port, nada. Reinstalling xserver* did not work either.
May the gods of stack overflow smile upon you for that EDIT line, because plugging only after boot was complete, it did work for me as well.
This is quite interesting, as I am running 20.04. This issue came out of nowhere, just turned on the computer and voila, it was not working. There had been no updates, no changes that could affect this during previous session.
Would love to know if someone else has bumped into this problem.
We know that eclipse kura can be installed on edge devices and Raspberry pi is the most popular edge device at now.
As per https://www.eclipse.org/kura/downloads.php, we can see various downloads for Raspberry pi, Intel Edition, BeagleBone and Fedora with the beta release.
But we couldn't see the download link to install it on Linux machines or VM. (Ubuntu or centos VM ). We want to install it on ubuntu machine and possible to view web UI on that machine.
EDIT(edit the question)
Is that possible to install only on Fedora ?
What are the complete steps to install kura on ubuntu or Centos ?
I believe the question was asked and answered here. To summarize, there is no generic installer for Ubuntu, Fedora, or CentOS. Kura has dependencies on both the OS and CPU architecture. The supported platforms are:
Raspberry Pi based on Raspbian: Raspberry Pi, Raspberry Pi B+,
Raspberry Pi 2/3
BeagleBone Black based on Debian
Fedora 25 ARM
Intel Edison
The "No Net" versions of the posted installers will remove most of the OS dependencies. For CPU architectures, if you are using something other than ARMv6 HF or x86_64, you will need to compile the native libraries. The minimum native library needed for Kura to start is udev.
im running Ubuntu 14.04.1 LTS (desktop), on an embedded device (Odroid U3) and
on boot, my 3G usb modem is seen as a ttyACM0 / ttyACM1 device, which is correct.
Post boot i am able to simply run wvdial..and from there I can get a connection...
I am running my system headless, and would ideally like to get the OS "converted" to more
of a server configuration(smaller) if possible. I have tried running the
the ubuntu server version here viewtopic.php?f=77&t=5123, along with
multiple versions of debian(7 / 7.4) but neither will detect the usb modem correctly on boot.
I am a newbie to linux, and the only thing that I have tried is
trying to force load some of the kernel modules on boot ( /etc/modules ) to try to
alter the detection of the device on boot. (cdc_acm, usbserial, ppp....etc), no luck.
On the ubuntu server version above I even updated the kernel to
version newer than the one currently on the working desktop version, still no luck,
Does anyone have experience with usb 3G modem detection on boot??,
Any ideas why it works on the 14.04.1 LTS desktop version , and not any others?,
thanks a ton...for any suggestions
Appears that there is a patch in 14.04 ubuntu boot that fixes the usb_modeswitch issues. After taking a raw ubuntu , adding usb_modeswitch , its now working just fine.
Did not even have to configure usb_modeswitch.
I'm using CubieBoard 1(A10), it have an Image of Linux Linaro to Run from MicroSD on its DVD. it has the sound drivers for HDMI and AUX Jack. in the "/proc/asound" there are some folders "Card0, Card1, Sun4iCodec, sun4isndhdmi". and I can Play Sounds and get the output from AUX Jack.
the problem is I need to build the kernel of Linux myself, so when I tried, the drivers would not install. I Included all of the sound Drivers in kernel, I tried every thing I could, but it doesn't included the Driver for AUX Jack or HDMI.
Any Idea how to install it?or how can I get the Drivers?
the kernel version of Image on DVD is: "3.0.57" and the version of kernel I use is: "3.4.67"
I have a HP Envy 4 1025tx machine with Ubuntu 12.10.
My blender doesn't seem to detect the dedicated G-Card ATI Radeon 7670m.
But it does detect it on windows. Should I have to install any linux drivers
or does blender doesn't fully support openCL on linux. Or shoulf I manually
recompile the code?
How should I fix it?
open the terminal and use the command: CYCLES_OPENCL_TEST=true
this enable the opencl support to opencl on blender
