[solved] mint 19.1 not playing sound anymore

[mm1992]

It has worked before, and at some point it stopped working, but I can't pinpoint when. Its sometime in the past 2 weeks or so.

:~$ aplay -l
aplay: device_list:270: no soundcards found...

The device I want to use is number 2, the integrated analog out on my mobo. Its a realtek ALC892.

Hi mm1992.

Usually, a sudden disappearance of sound can be fixed by deleting the files in ~/.config/pulse then running pulseaudio -k in the terminal.

I'm suspecting that may not be the case in your situation with no drivers loaded/running from your inxi report. I'm wondering if you uninstalled some application recently that took out alsa-base along with it (or some other necessary sound bit.)

See if this gets the driver showing in inxi again:
apt install alsa-base pulseaudio libasound2

They may say they are already the most recent version, or might install any of them if they got uninstalled somehow.

Good luck.

[mm1992]

Tried both of those, no dice. Those 3 packages were all installed. I then tried purging them, and then reinstalled them (apt-get install...) along with all of the other stuff they took with them. Same results for inxi -Fxz and aplay -l that I had before.

[MrEen]

Have you done a complete shutdown since this started?

If dual booting with Windows, does sound work in Windows?

You didn't happen to set up the RAID configuration some time in the past 2 weeks or so, did you?

Wild stab in the dark here. Try sudo alsa force-reload in the terminal.

I'll keep trying to think of other things to try/check.

[mm1992]

Yes to the complete shutdown, not dual booting, but I have had it working on this computer before. RAID was setup when I did the last install, and it was working after that. I tried the force-reload and it said there are no driver modules to reload

Let's give sudo modprobe snd_hda_intel a shot.

Let's give sudo modprobe snd_hda_intel a shot.

Code: Select all

modprobe: ERROR: ../libkmod/libkmod-module.c:192 kmod_module_parse_depline() ctx=0x55890b76a260 path=/lib/modules/4.15.0-45-generic/kernel/sound/pci/hda/snd-hda-codec.ko error=No such file or directory

modprobe: ERROR: could not insert 'snd_hda_intel': Unknown symbol in module, or unknown parameter (see dmesg)

[MrEen]

Using your File Manager, see if /lib/modules/4.15.0-45-generic/kernel/sound/pci/hda/snd-hda-codec.ko really doesn't exist please.

Also check dmesg | grep snd to see what it says.

[mm1992]

That folder is empty. There is also a 4.15.0-20-generic folder that has that .ko file, but there is nothing if I follow the path with the 4.15.0-45-generic folder.

Also check dmesg | grep snd to see what it says.

That command doesn't return anything.

edit- just rebooted and selected 4.15.0.20 in grub. When I logged in the sound worked as expected.

[MrEen]

Okay, it sound like the kernel upgrade broke your sound. I'm not comfortable being the one to give instructions on reinstalling a kernel so try this first: apt update followed by apt install -f
Maybe that'll fix it without reinstalling the kernel.

[mm1992]

Nope, those didn't do anything. But thanks, with your help I was able to identify the issue and now I can get it fixed.

[MrEen]

No problem. Glad we could at least figure out what caused the issue.

[raphabatagini]

Hi guys!

mm1992, could you please share with us the solution that you have found?
I'm having the same issue as you and can't figure out what to do to get rid of it.

[MrEen]

Hi raphabatagini, and welcome to the forum.

mm1992 hasn't been on the forum in over a month, so let's see if we can help. Let's start with the outputs of inxi -Fxz, aplay -l and lsmod | grep snd please.
