alsa-driver package

No sound, and sound card not found

Asked by Patrick

This started after unplugging an audio cable from my computer. I've tried everything in https://help.ubuntu.com/community/SoundTroubleshootingProcedure and a few other things. I know the speakers and sound card work because they work fine when I'm using Windows. When I open pavucontrols, the output tab only shows a dummy device with a dB bar that fluctuates when I play music.

It seems that you are missing the driver package with among others the sound drivers, probably linux-modules-extra-5.11.0-22-generic

How did you install this version of the kernel?

it must have been installed when I was following the steps in https://help.ubuntu.com/community/SoundTroubleshootingProcedure

Installed linux-modules-extra-5.11.0-22-generic and (prompted by of the output from that command) linux-headers-5.11.0-22-generic. Copying the output from both commands in case it helps, and for my own reference.

I do not see any step in https://help.ubuntu.com/community/SoundTroubleshootingProcedure which would instruct installing the 5.11.0 version of the kernel.

What do you now receive for

dpkg -l | grep ' linux-'
sudo modprobe -v snd_hda_intel
sudo lshw -C multimedia

Revision history for this message
Patrick (patreeceeo) said (last edit ): 		#7

Does step #1C do that by including linux-image-`uname -r` in the list of packages to install? Not sure to be honest.

Here's the output from those commands:

The command with linux-image-`uname -r` only re-installs the version of the kernel that is already installed at that time and does not install a new one.

Anyway, does sound work now?

Yes, thanks for your guidance!

Do you think that adding the snd_hda_intel kernel module (with modprobe) is what fixed it?

"Do you think that adding the snd_hda_intel kernel module (with modprobe) is what fixed it?"

The cause of your problem was that you did not have the complete set of kernel packages installed. The linux-modules-extra-* package was missing, but the sound driver is contained in that package. The solution was installing that package and after installation the module had to be loaded (with the modprobe command). After a reboot that module will hopefully be automatically loaded, so repeating this command should not be necessary.

Well, the problem began when I unplugged a speaker from my computer's audio out AUX port. It was working fine just before that, and I wasn't messing with the kernel until the problem started. The action of unplugging may not have directly caused the kernel packages/modules issue, that may have been the result of my attempts to fix the audio myself before coming to this forum. Just wanted to point this out in case this happens again and someone knows how the seemingly harmless action of unplugging speakers could cause Linux sound issues.
