Soundcard disappeared after no update, Dummy Output only
by Odk from LinuxQuestions.org on (#50Z2F)
Hi guys,
this is my first question on this server, I know, that this kind of problem has been around many times and I'm sorry about it, but I tried every solution I found during the day and nothing helped. I'm a beginner with Ubuntu with only a few months of experience, what's making the situation for me even harder.
I didn't do any update or upgrade yesterday and everything worked fine, but today when I turned my laptop on I got no sound, just Dummy Output.
I went through countless pages on forums, tried almost everything, but no success (removing and reinstalling ALSA packages, installing further audio add-on packages, adding my user to groups and so on). I can't even run alsamixer (Mixer attach default error: No such file or directory).
I also tried commands from, for instance, this link: https://askubuntu.com/questions/1123...d-not-detected .
Again with no effect.
Here's more information about my situation:
lspci -nnk | grep -A2 Audio (returns nothing)
aplay -l (no soundcards found...)
pacmd list-cards (0 card(s) available.)
sudo fuser -v /dev/snd/* (returns nothing)
grep 'audio' /etc/group (audio:x:29:odk,pulse)
Only with lshw I can find in *-multimedia Multimedia audio controller (Intel Corporation) and lspci -v detects 00:1f.3 Multimedia audio controller: Intel Corporation Device 9dc8 (rev11)
*pavucontrol* detects only Dummy Output.
Here's the link to alsa-info for more detailed information:

Thank you for any help or advice!
