No Sound After A Linux Kernel Update


So I updated the Linux kernel from 5.4.12 to 5.4.13, after I updated the kernel, I don't hear any sound.


Is there any way to solve this?

Hello 100000EE!

Unfortunately, very few of us here at LQ.org are psychic. You're going to have to provide us with as much info as you can when you ask questions like this if you really want someone to attempt to help you.

What kind of info, you ask? Well, simple things for starters...

- your operating system?
- what version?
- how did you update?
- sound device info?
- et cetera...

The more info you can provide, the quicker and more easily folks here who would like to help you can actually do so.

Regards,

~Eric

You should still have the ability to boot to the prior kernel. Try that and see if the sound works and also what driver it is using.

It is not uncommon for kernel updates to change drivers. If all that happened is a kernel update then I'd tend to suspect that. Be sure to do a full power down and leave it for 20 minutes before rebooting just to be sure nothing is hanging up.

Looking at your previous posts, I see you're using Slackware current. Actually, there don't seem to be any stable distros using that kernel version. Perhaps you should be using a disto which is a little more friendly, or asking the moderators to transfer your post to the Slackware section where more people will be looking?

Ok, the operating system I'm running is Slackware 15 (current).
How did I update? I compiled the kernel.
Sound device info? well, it's some integrated sound card, but when I did the aplay --list-devices command, it says this.

Hmm...

If #aplay -l gives you no output, that's not good. It should look something like this:

Code:
root@ericsbane07/home/vtel57:# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC889 Analog [ALC889 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1

  Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
Do you have inxi installed on your system?

#inxi -A

Code:
root@ericsbane07/home/vtel57:# inxi -A
Audio:     Card-1 NVIDIA GF114 HDMI Audio Controller driver: snd_hda_intel
           Card-2 Advanced Micro Devices [AMD/ATI] SBx00 Azalia (Intel HDA)
           driver: snd_hda_intel
           Sound: Advanced Linux Sound Architecture v: k4.4.208
When you say you compiled your own kernel, I'm assuming you mean a "custom" compile? If so, my guess is you made a boo-boo somewhere in that process.

So now I recently installed inxi on my system, here are my sound devices.

If everything else is working, this is probably going to be some little stupid thing that's causing your problems. I'm going to have to think on it a bit.

Stand by for assistance from others here, possibly.

Oh, and if you solve issue in the meantime, please let us now what/how you did it.

Everything else is pretty much working on my system, to be honest.

Well then you have to tell us how, all steps in most excruciating detail, so we can find out together where you misconfigured something.

Actually, I won't be able to help with that, but I know that much more information is required.

Also, just compiling it does not automatically make the system use it.

Or guarantee that it will work at all.
