What steps did you take to upgrade your kernel? Was it along with the usual mass upgrade steps like:

Code:

slackpkg update
slackpkg install-new
slackpkg upgrade-all
slackpkg clean-system

Do you take any special precautions around blacklisting kernel packages and doing manual upgrades? Perhaps you missed upgrading the kernel-modules with the kernel? Maybe see what the following reports to make sure you have modules from the same version as the running kernel installed?

Code:

find /var/lib/pkgtools/packages/ -name "kernel*$(uname -r)*"

Some info about your audio device and sound server might be helpful. Whats the output of:

Code:

inxi -A

Anything suspicious about audio devices/drivers in the output of dmesg?

Hello, thank you for answer. I didn´t use slackpkg clean-system (didnt know about this command), and didn´t take any precations about blacklisting kernel upgrade. And Iḿ really sorry for that. About dmesg didnt see anything about sound, but looks like it is with lots of errors.

Code:

root@darkstar:~# find /var/lib/pkgtools/packages/ -name "kernel*$(uname -r)*"
/var/lib/pkgtools/packages/kernel-source-5.15.145-noarch-1
/var/lib/pkgtools/packages/kernel-headers-5.15.145-x86-1
/var/lib/pkgtools/packages/kernel-generic-5.15.145-x86_64-1
/var/lib/pkgtools/packages/kernel-modules-5.15.145-x86_64-1
/var/lib/pkgtools/packages/kernel-huge-5.15.145-x86_64-1



root@darkstar:~# inxi -A

I't would also help ius be better able to diagnose and solve the OPs problems if he/she would post log files either via a service like pastebin.com or via use of the code flags on the LQ forums.

Everything looks in order as far as having all the kernel packages up to date, the kernel driver is in use, alsa is running, and you are using pulseaudio. You should be getting sound...

Are you running in a desktop environment? Or only on the command line? If its just command line did you look through 'alsamixer' (pulseaudio master slider or mute button, and soundcard output sliders and mute buttons on the F6 pane). I've sometimes had the mute toggled after swapping outputs around. Otherwise if you're in a desktop environment, run pavucontrol and do a similar check over that.

did you update your initrd after upgrading the kernel?

I didn´t know about pastebin.com, sorry, but it isn´t oppening the site now, I will try it later.

I'm running kde, pavucontrol looks fine. But alsamixer looks like the wrong card is selected, I figuring how to change.

Yes, after the kernel upgrade I didn´t paid attention to the message about initrd, needed to run a iso to correct my mistake.

I'm almost giving up and formatting again, but I am trying to learn how to correct first.

I resolved to try KDE with root user and the sound back again. Before going back KDE with a user account I did a xwmconfig change kde to fluxbox and back to kde and the sound is back again. Don't know why. Thank you all for the help.
