Soundcard dissapears after today's update

English Hardware
1

Hello. I have no audiocards (against “Dummy”) now after today’s update. Some forums said it’s because linux kernel or you need to add your user to the audio group

sudo gpasswd -a "your user" audio
sudo reboot

I made adding to group but I again have no soundcards. And I think I need to add the properly one or do something to restore the audio

$ cat /proc/asound/cards          
 1 [Dummy          ]: Dummy - Dummy
                      Dummy 1

$ cat /proc/asound/modules        
 1 snd_dummy

If it’s matter, my system repo is Packman. According to this manual
http://opensuse-guide.org/codecs.php

Afterwards make sure all your multimedia packages are coming from the Packman Repository:Start YaST Software Management => Click on View => Click on Repositories => Select the Packman Repository => Click “Switch system packages” => Click “Accept”

P.S. I use a notebook Lenovo Thinkpad T470p now. So, the driver can be Realtek but I can’t find it in the soundcards list

No hardware recognised by ALSA.

Let’s see how it appears via lspci (class 04 devices are for audio)…

/sbin/lspci -nnk |grep '\04' -A3

Nothing happens.



simple /sbin/lspci:

And I just reinstalled SUSE (without /home dir. It’s previous). The same problem occurs. Then I installed the codecs.
Tried with another user - nope

There is no audio hardware detected. That could be due to a failure of this hardware device. (Even without a driver present, the relevant chipset should be reported.)

That’s not surprising given no audio hardware enumerated with the lspci command.

Based on what I’ve found on this Lenovo page it is possible to remove the audio card, so perhaps it is just not seated correctly? That would be worth investigating first. The audio device should be listed as per this archlinux wiki page.

After shutdown and loading SUSE yesterday the sound was played via my headphones and the soundcard appeared. But after closing the notebook and open it again sound dissapears (soundcard is still here). So I clicked to edit in in Yast and it autoinstalled.
So the sound in the headphones became very loud but it was not reacted by master volume changing (I down the volume to 5% and it plays like at 150%) BUT if I set the volume to 0% it mutes. Ok, the sound is not reacted by hardware changes BUT it reacted well to software changes (SMPlayer program’s personal sound).
Today I opened the notebook again and there is no sound (try to play with dynamics, not headphones). The soundcard is still here. It’s intel HDA. “snd-hda-intel”

So I think I also need to configure switching from phones and dynamics properly.

P.S. some old 2010 ubuntu forums sayed that the problem to load souncard drivers can be in GRUB. Don’t know

$ sudo lspci | grep Audio
00:1f.3 Audio device: Intel Corporation Device a171 (rev 31)

hmm there is no sound at all from the last moment. Need to configure it.

yeah, a made huge update now with kernel update and soundcard dissapeared
but I can see it in YAST’s Sound

$ sudo lspci | grep Audio

none

The update may have provided a new kernel version. The alsa sound driver will come with the kernel version. So a reboot (to load new kernel with new sound driver) will be needed after a kernel update.
