No Sound on Kubuntu 19.04

[salwigy]

Mine was solved minutes ago after the command

sudo apt install alsa-base pulseaudio
sudo alsa force-reload

And a restart, fix the sound problem, thanks to all

[Don B. Cilly]

Oh well
Actually, I never had to reinstall pulseaudio on Neon, only on Kubuntus.
And it never uninstalled anything else - that I was aware of.

Or maybe I used a different procedure... probably added

apt moo

at the end... or something

[claydoh]

If reinstalling pulseaudio "caused other things to be uninstalled as well"... hmm...
(and may I point out that reinstalling pulseaudio when sound is not working is not exactly random)
... when that sort of thing happens, in my limited experience it's usually a disk failing.

Me, I would try to run fsck or some disk utility from another system or a Live USB, and see what it says.

I may be wrong -only trying to help - but I've had sound fail more than once and reinstalling pulseaudio always worked.

If you are on Neon still, there may be a difference in the dependencies to what Kubuntu has (not 100% likely, but very possible, but more so if you are running the dev-unstable branch)

IThe packages you suggested to remove also uninstalls a number of other things, and even more if an autoremove is run, as the command output suggests in the top half, as they are not needed when those two are gone.

Do you want to continue? [Y/n]

When reinstalling alsa-base and pulseaudio, NONE of the other packages removed are reinstalled.
As I did state, none of the the things removed along with the two would have caused the OP's problem, unless they did do an autoremove, which does not seem to be the case as the plasma-desktop-data package was still present on their system.

What might work on your specific hardware is not a guarantee that it will work on someone else's hardware.

I did cnrl - alt - t and got to the terminal. ran the commands and it now is back and working. Thank you very much for your help!
Also the sound is working

[claydoh]

I am in the root. Running in recoverymode I can get to the root user. I ran the apt plasma-desktop-data command and it says it is already at the latest version

Try apt reinstall instead. The image you posted is saying there is a missing file, and this package is what provides this file.

You can get to a full screen terminal from the desktop by using ctrl-alt-f2
And then back to the desktop with ctrl-alt-f1.

Also try installing kubuntu-desktop and plasma-desktop, which may also pull in some missing items


While Don's suggestion to uninstall some things also caused other things to be uninstalled as well, things not added back using his second command, those extra bits are not essential, and should not be causing your problem as far as I can tell, so you may be having other issues besides the sound not working.

Can you give more info, such as what make and model of system you have?

I may not be able to respond myself too quickly as I have to go back in to work shortly, but hopefully others will jump in and help as well.

I am in the root. Running in recoverymode I can get to the root user. I ran the apt plasma-desktop-data command and it says it is already at the latest version. Also ran the other two commands. I get the same results

[panch0]

I dont have access to the terminal.. l

[claydoh]

Something important was removed along with the pulseaudio packages.

see if (re)installing these fixes things:

plasma-desktop-data plasma-desktop kubuntu-desktop
for example:

sudo apt install plasma-desktop-data

Probably only the first one is needed, but the others two should make sure any other missing Plasma bits are pulled in.

[panch0]

I did an update on everything the ran the commands above. Then rebooted system and that's what it boots too now. What hardware would you need to know.

[claydoh]

Getting some hardware info would be useful here, especially before suggesting a random package removal/reinstall, which seldom work, if ever.

[panch0]

let see if this works

[Don B. Cilly]

Can't see it I'm afraid.
Can you attach it here?

[panch0]

The error I recieve is here. https://ranchoconcepcion.s3.amazonaw...808_112900.jpg

[panch0]

I tried that and now it wont boot back. It give me an error like kde or something isnt installed. I dont have access to the terminal either. I will boot to that screen and post it here
