No sound on Ubuntu 20.04, Lenovo Thinkbook 14s G2

Question

I just installed Ubuntu 20.04 and everything, aside from the sound, works flawlessly. The weird thing is that when the audio is triggered (by a system sound, muting/unmuting) there's a weird bleep (sounds like something being deflated). And when on wired headphones, there's only static. Bluetooth headphones work I guess because it's another interface?

I've tried upgrading the kernel, I also looked into some other similar questions, but it seems this is something different.

Here's the output for sudo lshw -C multimedia @sancho.s

Check if https://askubuntu.com/questions/1258510/only-dummy-output-sound-in-ubuntu-20-04-after-reboot-broken-driver-modul or the answers there help — sancho.s ReinstateMonicaCellio, Mar 22 '21 at 13:16
As a first step, install linux-modules-<kernel version>-generic and linux-modules-extra-<kernel version>-generic. — sancho.s ReinstateMonicaCellio, Mar 22 '21 at 15:45
You can try installing pavucontrol package and playing around with it to see if it displays anything useful pointing out the problem. — WinEunuuchs2Unix, Mar 22 '21 at 18:17
Hi @rsoto, have you find the solution? I've the same problem but it seems it happens only when I restart windows and enter ubuntu, but it is fixed once I turn off the laptop, and then turn it on again (not restart) and enter ubuntu. — fikr4n, Mar 24 '21 at 01:37
Why not showing us your hardware? Please [edit] and copy/paste the output of sudo lshw -C multimedia and poke me — cmak.fr, Mar 25 '21 at 10:33
I would also check in Ubuntu Settings/Sound if output device is properly set. There may be more than one sound device, and Ubuntu sets the wrong one as default. — qba-dev, Mar 25 '21 at 12:30
Make sure the sound driver is installed correctly on Ubuntu 20.04. It might help. What computers are not affected? — Nimmam, Mar 25 '21 at 13:43

It seems the driver you are using is sof-audio-pci. As per this, you may try with snd_hda_intel. Simply copying the procedure:

Edit grub
```
$ sudo gedit /etc/default/grub
```

Change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"

Update grub
```
$ sudo update-grub
```
Reboot

You can check if soundcards are detected with

$ aplay -l

If that doesn't work, it may help if you post the output of:

$ cat /proc/asound/cards
$ lsmod | grep snd
$ dpkg -L linux-modules-<kernel version>-generic | grep snd
$ inxi -SA
$ lspci -nnk | grep -A 4 Audio
$ uname -a
$ aplay -l
$ dpkg -l | grep alsa
$ grep intel /etc/modprobe.d/alsa-base.conf

So, I'm not sure what happened, but I updated grup as instructed, then I rebooted and sound output was still not working, but not only that, input was not even showing as a recognized device. So I edited grub again to rollback changes and start running those commands, and then I tried rebooting but got a black screen for 3 mins or so, so I forced a shutdown and when I got back the sound was working! – rsoto Mar 25 '21 at 15:25
@rsoto - So now you have everything working as it should? What is now left in your grub line? Which driver are you using now (sudo lshw -C multimedia)? It is good that you take a few minutes to provide feedback, for the benefit of the community. – sancho.s ReinstateMonicaCellio Mar 25 '21 at 16:01
sure, I'll be updating the question with the output for those commands. The grub line is as it was originally, with quiet splash – rsoto Mar 25 '21 at 16:13
@rsoto you accepted the answer, has it been solved? – fikr4n Mar 26 '21 at 01:43
@fikr4n yes, it has. – rsoto Mar 26 '21 at 21:53
