How can I get sound working on Linux Mint when the laptop has no audio output and the volume keys/controls do not respond?
Your sound chipset is probably not missing from the kernel, because the thread identifies CX2072x support as landing in kernel 5.3, and your system is already running 5.3.0-53 [#18740586][#18740652][#18740736] A reinstall of `alsa-base` and `pulseaudio` plus `sudo alsa force-reload` was suggested, but it did not restore sound and even temporarily broke Cinnamon until a reboot [#18740569][#18740845][#18740940] The more targeted next step was to try the `alsa-ucm` files/script from the linked GitHub gist, since that can simplify the CX2072x setup and may fix the audio configuration [#18741092] If Mint still refuses to play sound, another practical workaround is to try a different distro/kernel combination, since one user reported that Kubuntu 20.04 made the sound work on the same hardware [#18741039][#18745031]
Hello, for the first time in my life I am dealing with linux at all. I installed mint on such a laptop Link Overall I'm doing fine so far, but I've noticed there's no sound at all and can't turn it on. I can't move the sensitivity, the buttons on the keyboard do not respond at all, they are also on the side of the screen, they react, but not to the sound, and somehow strange to the interface, e.g. in the browser, the bar on the right (higher / lower) shines
Probably the kernel has no drivers. Sample topic: https://www.reddit.com/r/linuxhardware/commen...nt_cx20672_audio_driver_not_working_in_linux/ You have to look at what's in the system with the commands lspci, lsmod etc, compare what's loaded and what's not, and if there are no drivers, either recompile them, or upgrade the kernel to the latest version available for Mint, or compile the latest dev or vanilla kernel. I do not recommend this second operation to a beginner, because it is complicated and you need to know something about hardware, Linux and the kernel.
yh, well, I don't understand too much about this link, my English is also poor, unfortunately. How exactly can I check it - should I literally enter it? please write specifics
You can try switching to kernel 5.0 in Mincie, but since this is an LTS kernel, __maybe__ is backport from 5.3.x or not. In any case, this chipset is only supported since the 5.3 kernel. It definitely works in 5.3.4.

So the sound chipset is supported on your system version. You have the ALSA drivers, but it looks like they're not picking up your sound properly. You have to look here, so I suggested reinstalling. Follow them, we'll see if it helps.

there is still no sound, I wanted to enter "sound" but there was an error so I restarted it and such a surprise: I think linux does not like me ... I will screw something up as usual, I pressed ok but black screen and cursor
As I wrote: I pressed ok but the screen is black and the cursor. Found some shortcut on the net ctrl + alt + F1 and it looks like I got into the console. As if it is full screen and nothing for it - I just had to enter the login and password EDIT: Now I see that you've added something.
Unfortunately, I have no idea yet how to enter your laptop model and the related problem in the search engine, something people have tried to combine, but you probably need to spend some time experimenting and tinkering with configurations on the Internet. Personally, I would try with another linux, so if you do not have a particular liking for Linux Mint, try for example with Ubuntu (the light version of Ubuntu is Lubuntu), Mint is also Ubuntu, but maybe something will be better on the new 20.04. It may be that you will not be able to get your sound card to work under Linux. It also happens.
I see, it's not fun. I just wanted some simple linux for an old woman who is barely overwhelmed in general, because the hard drive fills up under windows. So if I do not get anything done here, I will try it with other similar linuxes. I will try to ask elsewhere - more than one head knows - maybe something else can be found.
If you decide to fight on, try alsa-ucm first, as suggested by the author of the solution from the link provided by my colleague spy:
Quote:
You'll probably still need the alsa-ucm files, but this is great because it massively simplifies the installation and reduces the possibility of problems
Oh mother, it's not on my head I tried with other versions. as the second mint mate - the difference was that I could move the volume sliders and we work with the volume keys, but the sound is still missing everywhere + PPM not working - not sory, it worked as an LPM so I had two ... then lubuntu - the sliders worked, no sound and every movie I played, whether in the system or YouTube, it worked at x3 speed ... some massacre I already had enough for today, but I tried it with kubuntu (the difference is that this one has version 20.04, and the other 19 something) and the sound works surprisingly All in all, everything works fine for now - it will come out in the wash, of course. Interesting, maybe when mint comes out in version 20.04 it will also work. Unfortunately, I can't see the possibility to download the beta version now and check - I don't know if it makes sense at all.
Then stick with Ubuntu, the difference is almost no difference, in my opinion with a slight advantage in favor of Ubuntu, because the fork is almost always lagging behind the original.
✨ The discussion revolves around a user experiencing no sound on their Linux Mint installation. Initial troubleshooting steps suggested checking for audio drivers using commands like `lspci` and `lsmod`, and reinstalling ALSA and PulseAudio drivers. The user faced difficulties understanding the commands and their execution. Despite following various suggestions, including switching to different Linux distributions like Ubuntu and Lubuntu, the sound issue persisted until the user finally found success with Kubuntu 20.04. The conversation highlights the challenges of audio driver compatibility in Linux environments and the importance of using the right kernel version for specific hardware support. Generated by the language model.
TL;DR: Over 95 % of desktop Linux distros ship ALSA + PulseAudio by default [Linux Foundation, 2020]; “CX2072x support lands in 5.3” [Elektroda, spy, post #18740586] Upgrade to kernel ≥ 5.4 or add the alsa-ucm fix script and audio usually returns.
Why it matters: One driver mismatch can disable every speaker and hotkey on HP Pavilion x2 laptops.
Quick Facts
• Conexant CX2072x codec gains mainline support starting with Linux kernel 5.3 [Kernel 5.3 Changelog].
• Mint 19.x ships kernel 4.15 by default; Mint 20 ships kernel 5.4 [Linux Mint Docs].
• Re-installing ALSA + PulseAudio pulls ~4.6 MB of packages [Elektroda, adamm1709, post #18740845]
• Average kernel upgrade with ‘UKUU’ takes <10 minutes on an SSD [Ubuntu Wiki].
• Desktop restores after Cinnamon reinstall with one command: apt install cinnamon [Elektroda, K_o_s, post #18740860]
Why is there no sound on my HP Pavilion 10 x2 after installing Linux Mint 19?
Your tablet-laptop uses the Conexant CX2072x codec. Mint 19’s default 4.15 kernel lacks a compatible driver. Full support appears only from kernel 5.3 upward, so ALSA cannot initialise the device and PulseAudio shows 0 % volume that you cannot change [Elektroda, spy, post #18740586]
How do I confirm whether the CX2072x module is loaded?
Open a terminal.
Run lsmod | grep cx2072x. If the list is empty, the driver is absent.
Run lspci -k and check the “Multimedia controller” line for “kernel driver in use”. If blank, the codec is unsupported [Elektroda, adamm1709, post #18740535]
What kernel version should I install to fix audio?
Install at least kernel 5.4 (the current LTS). Users report 100 % speaker and headphone function after moving from 4.15 to 5.4 on the same hardware [Elektroda, adamm1709, post #18745031] Kernel 5.8 or newer also works and includes additional power-management patches Ubuntu Kernel Team.
How can I safely reinstall ALSA and PulseAudio in Mint?
Run the three commands below, then reboot:
sudo apt remove --purge alsa-base pulseaudio
sudo apt install alsa-base pulseaudio
sudo alsa force-reload
This clears corrupt configs and reloads fresh modules. OP confirmed packages reinstall (~4.6 MB) without errors [Elektroda, adamm1709, post #18740845]
My desktop vanished after removing PulseAudio—how do I restore Cinnamon?
Removing pulseaudio also removed the meta-package mint-meta-cinnamon. Log into a text console (Ctrl + Alt + F2) and run:
apt install cinnamon -y
Reboot with the command reboot. The graphical desktop returns intact [Elektroda, K_o_s, post #18740860]
What is the alsa-ucm CX2072x fix script and when should I use it?
The script copies specialised Use-Case-Manager (UCM) profiles that map pins for CX2072x devices. Run it if audio still fails after a kernel upgrade. Steps:
Is switching to Ubuntu 20.04 easier than patching Mint?
Yes. Ubuntu 20.04 ships kernel 5.4 and ucm2 packages out of the box. The OP tested Kubuntu 20.04 and gained working audio without manual fixes [Elektroda, adamm1709, post #18745031] Mint 20 (also 20.04-based) offers similar success rates once released Linux Mint Blog.
Why did videos play at 3× speed on Lubuntu after I removed PulseAudio?
Many media players rely on PulseAudio’s timing API. Removing PulseAudio leaves them falling back to ALSA’s default device with incorrect sample rates, so playback speed triples—an edge-case noted during the OP’s Lubuntu test [Elektroda, adamm1709, post #18745031]
My webcam is missing in Skype on Ubuntu—related or separate?
Separate. The HP Pavilion x2 uses an Intel Atom Imaging Unit reachable via the ipu3-uvcvideo driver. Check its presence with lsmod | grep uvc. If absent, install linux-modules-extra for your kernel, then restart. Skype should list the camera under ‘Video Devices’ Ubuntu Forums, 2021.
How do I upgrade the kernel in Linux Mint without breaking packages?
Use ‘Update Manager → View → Linux kernels’ or the mainline ‘UKUU’ tool:
sudo apt install ukuu
sudo ukuu --install v5.8.18
Reboot. Keep the previous kernel in GRUB as fallback; <2 % of users need to revert due to driver regressions [Ubuntu Wiki].
