Can anyone please share what `hdajackretask` shows? It's a part of the `alsa-tools-gui` package. 
In the top left where it says "Select a codec", choose `Realtek ALC285`. Then can you please list the pin configuration? For example, what each pin ID is and what the dropdown box says.

I tried using the gist script earlier in this thread to install the sof drivers, but that broke things, so I uninstalled it all. Now my audio is noticeably lacking any kind of bass frequencies. I'm curious if one of the speakers is being unused now.

Here is also my alsa-info.sh output

Dummy Output after following these instructions - no sound whatsoever!

2020-03-26, 9:03 AM

I have the same problem - after following some instructions in the first 3 or 4 pages of this thread, I no longer have ANY sound - the device is "Dummy Output".

 

Ubuntu 18.04, 5.3.0-42-generic.

 

I tried to remember what I did and undid the changes, but my machine may be in a odd state.

 

`sudo alsa force-reload` didn't help.

 

`alsamixer` says `cannot open mixer: No such file or directory'

 

`dmesg | grep SOF` shows nothing

 

`dmesg | grep sof` shows this (besides some "Microsoft" matches):

Please help. I have no idea how you guys come up with those cryptic commands and IDs like 63BE270F-1C11-48FD-A6F7-3AF253FF3E2D (?!). I just want basic sound and I can wait a month until the Ubuntu 20 LTS release which allegedly fixes this mess. CC @tokyovigilante.

 

PS: also, this forum broke things. Links to posts no longer work, e.g. the one to Dave's instructions from this post, and apparently "Reply" doesn't link to the replied-to post any more. CC @Mark_Lenovo @MarkRHPearson.

I had this same issue. I believe it is related to a recent kernel update rather than changes in this guide (as I didn't make any of those changes and still had the same issue). The solution for me was to add "snd_hda_intel.dmic_detect=0" as a boot parameter in Grub. See https://askubuntu.com/questions/1218041/ubuntu-18-04-audio-disappeared-after-update for further details.

@deekue Thank you!

 

I have the same model purchased recently and after upgrading bios / firmware on Windows I attempted to install Kubuntu 19.10 and the WiFi was not working. 

 

Following your method everything is working perfectly now. 

 

When I tried upgrading to kernel 5.6 though the WiFi stopped working again, I guess I'm going to sit on 5.5.10 for a while now.

Re:[Guide] X1 Carbon 7th Generation Ubuntu compatability

I am on Ubuntu 19.10 with my X1 7th gen. Kernel is 5.3.0-46-generic. I have good sound quality via headphones plugged in to the mic/headphone jack. The sound over the built-in speakers is having a flat feeling, i.e. the bass is rather non existing and overall it feels crispy. It does not matter if I select the stereo or the 4.0 output.

 

Is anyone else having this issue?

@deekue 

 

Thanks for this info.  I've upgraded to Ubuntu 20.04 with the 5.6.7 kernel.  Other than the later kernel I have all the versions you list below.  

 

The microphone and speakers work BUT I only have two speakers showing and not option to change.  Specifically:

 

Settings > Sound shows the device as "Cannon Point-LP High Definition Audio Controller",  the only Output Profile is "Play HiFi Quality Music" and Test Sound shows Front Left and Front Right only.

 

 

Installin pavucontrol and opening Pulse Audio Volume Control again shows only one Configuration available (here it was previously possible to set different speaker configurations even if they didn't work properly).

 

Does that match what you see or are you actually seeing 4 speakers in eg Test Sound?

 

Cheers

This is what I did to get everything working on my X1v7 20R1:

  1. Installed Ubuntu 20.04 (Focal Fossa)
  2. Installed Ukuu then used that to install the mainline kernel v5.5.10
  3. ran `apt update && apt upgrade` to get the latest versions of PulseAudio and ALSA
  4. ran `apt install tlp acpi-call-dkms` to get better power saving and throttling control
  5. reboot

 

I spent a while trying to crowbar fixes into Ubuntu 18.04 and 19.10 but it was a mess.

 

To get audio working required the latest versions of everything in the stack

  • SOF kernel driver snd-sof-pci (from kernel v5.5+)
  • SOF firmware (from linux-firmware >= 1.187)
  • ALSA packages (from alsa-ucm-conf and alsa-topology-conf >= v1.2.2)
  • PulseAudio (from pulseaudio >= 13.99)

 

now sound works with all 4 speakers, the microphone records clearly and the volume keys all do the right thing.

Re:[Guide] X1 Carbon 7th Generation Ubuntu compatability

Hello,

 

I have Ubuntu 20.04 LTS installed (actually installed it even before it went to BETA state) and sound and microphone works reasonably well - I'm using the recommended 5.3 kernel (at this moment is 5.4.0-25-generic).

 

I have an annoying problem tough (that I'm not 100% positive it's related with the sound drivers). The volume once in a while lower itself automatically, like one step down.

 

Anyone is having this problem?

 

I have Manjaro linux (up to date) will also 5.3.x kernel and sound and micro also works and this sound problem does not occur. Again, not sure if it's related with an application/some gnome config or the driver itself.

I'm on 20.04 as well and have not noticed that problem, but I will keep an ear up and let you know if it happens. All audio including mic works now although there's many long named audio devices available that doesn't seem to be in use for some reason.

Thanks for the reply. It might also be related with my external HDMI monitor sound output, since it adds a new output source.
