No sound Lenvo Yoga 9i Slim

Hi all,

After multiple issues, I hope this is the last one for this damned laptop, we got everything except for the sound.

Currently running with the following grub commands:

GRUB_CMDLINE_LINUX_DEFAULT="i915.enable_psr=0 atkbd.reset=1 i8042.nomux=1 i8042.reset=1 i8042.nopnp=1 i8042.dumbkbd=1 quiet splash intel_iommu=on"

If you have any suggestions, do let me know, in the meanwhile I'm going to browse some other solutions :slight_smile:


Try first;


To check the volume or if your card is muted.

Hi Storm,

I believe everything is in order:

Okay next is to check Pulse audio;

sudo apt install pavucontrol

Try differently setups there.

Are all sound outputs silent. e.g. speakers, headphone etc?
From Alsamixer hit [F5] All.
then post another screenshot of all the sound channels.

Whilst in there, look for a sound channel called "Loop-back". Try toggling that from Disabled to Enabled.


Something weird showed up, it says my speakers are unplugged?

As requested :slight_smile:
No loop-back to be found though!

However, your problem could be a Ubuntu 20.04 bug. See this:

I wonder if you are willing to try Z15.3 and see if you get sound with that?
