Dummy Output in Audio; nothing is working (ALSA broken?)
Problem: My audio is not working. I'm getting that "Dummy Output" in the sound settings. I've been scouring the web, but nothing I try is working. I've tried
sudo alsa force-reload
sudo apt-get remove --purge alsa-utils
sudo apt-get install alsa-utils
I've tried about every single little thing, and it's driving me crazy.

(wasn't quite sure how much you guys needed)
For some reason, I don't have a .asoundrc file or /etc/asoundrc.conf file. I can't get into alsamixer either. I've uninstalled, reinstalled, uninstalled, and reinstalled alsa-base, alsa-utils, pulseaudio, and even Wine.
I don't know what else to do at this point. Can you guys help me?
EDIT:
sudo alsa force-reload returns
Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).
Solution 1:
Thanks to GLauro for the pointer in the right direction. I experienced the same problem on upgrade to kernel 5.8.0.36. I attempted to modprobe the snd-intel-dspcfg module, and found by searching that it had been moved to the linux-modules-extra- package. So I had to install that package, since it hasn't been installed by default since 5.4.0-60.67
sudo apt install linux-modules-extra-5.8.0-36-generic
Then reboot
Solution 2:
After searching, I have found a simple answer. Just execute
killall pulseaudio
Your speakers should work fine now. To ensure this, test the sound stack in System Settings > Sound > Test Sound (Speaker test, Not Digital Output (S/PDIF) test)
The only problem with your issue is there is no driver found for your audio for that then Try to reinstall pulse audio and Alsa, open terminal and enter the following commands-
sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload
even Upgrading your sound drivers may fix the nosound issue , for that use the following commands -
sudo add-apt-repository ppa:ubuntu-audio-dev
sudo apt-get update
sudo apt-get dist-upgrade
the final try from me is to make some changes in speech-dispather by-
sudo gedit /etc/default/speech-dispatcher
and change
RUN=yes
to
RUN=no
hope these workarounds will solve your issue, before testing make sure to restart once after doing any of the method.
