<SOLVED> Sound not working on Lenovo L14Gen2

[luan23]

Hey there,

I‘m having problems with getting onboard audio on my Lenovo L14 to work.
I‘m running Linux Mint 20.1 with a v5.4 Kernel. I‘ve already tried manually enabling the snd-via82xx drivers, which helped, but the mic did not work and behavior was inreplicable.. After adding the driver to the grub startup and rebooting as in https://wiki.ubuntuusers.de/Soundkarten ... sprobieren, audio playback did not work and aplay -l and cat /proc/asound/cards showed, that no soundcard was found, even after loading the snd–via82xx again and reloading alsa.

I added my /etc/modprobe.d/alsa-base.conf below:

Any would be appreciated! Thanks a lot and greetings,
luan

Welcome to the forum, luan.

I‘m having problems with getting onboard audio on my Lenovo L14 to work.
I‘m running Linux Mint 20.1 with a v5.4 Kernel.

You have not provided any information about your hardware, but it may be that your system needs a kernel newer than 5.4 in order to get the correct drivers.

Please give us information about your install by entering this command in a terminal: inxi -Fxxxrz
Click </> from the mini toolbar above the textbox where you type your reply and then place your cursor between the code markers and paste the results of the command between the code markers [code]Results[/code]. This will let us know how Mint sees your hardware.

No, that is not all the relevant info. Please provide all the data I requested. It is the same data Section 5 of READ: How To Get Help! explains we need to be able to help you.

Your system has a very new cpu and is currently running without a graphics driver. You need to install a newer kernel than the default 5.4. Once the proper kernel is installed to get graphics, then we can see if there is still a sound problem.

Graphics:
Device-1: Intel vendor: Lenovo driver: N/A bus ID: 00:02.0
chip ID: 8086:9a49
Display: x11 server: X.Org 1.20.9 driver: fbdev unloaded: modesetting,vesa
resolution: 1920x1080~77Hz
OpenGL: renderer: llvmpipe (LLVM 11.0.0 256 bits) v: 4.5 Mesa 20.2.6
compat-v: 3.1 direct render: Yes

The driver for Intel graphics comes from the kernel. Let's start with the 5.8 kernel which is available in Driver Manager and see if you get graphics with it.

Open Update Manager. Select View > Linux Kernels and click Continue. Make sure 5.8 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear. Install the kernel and then reboot for it to become active.

After doing that, run inxi -Gx to see if the driver: N/A is replaced with driver: i915 and there is an Intel renderer.

If it remains N/A (which I think is likely since the cpu is listed as Tiger Lake) then try the 5.10-oem kernel. Install the latest 5.10-oem kernel with sudo apt install linux-oem-20.04b and then check the inxi -Gx output. That kernel has been working to get stable graphics for most people with 11th gen Intel processors.

Just installed the 5.8 version of Kernel, sound and mic working fine now also after rebooting once again!
Thank you so much for your help and easy-to-understand explanation!!!

Glad that worked to give you sound.

Do you also have a graphics driver installed with the 5.8 kernel? I'm curious which renderer corresponds to that cpu. Knowing that helps me to help others.

I think that is the case now, but not quite sure
