Sound not working on ubuntu 20.04

Question

at the very beginning sound was working using the motherboard line out jack. A few days ago the motherboard line out jack went bad. The sound is awfully robotic and unintelligible. The jack on the case front panel gives no sound at all (I hadn't tried it before, because I was using the motherboard line out on the back).

Computer is 3 weeks old:

I've tried many things: pavucontrols, reloading/restarting alsa and pulseaudio, adding lines like options snd-hda-intel model=auto, installing graphics card driver but nothing seems to work.

A few additional info:

pactl list sinks will tell us, what outputs you have and pactl list cardswill tell us about your hardware. Copy the result into your question as you've done with the other information — kanehekili, Mar 24 '22 at 19:19
I just updated the question with the outputs of those commands. The headphones are connected to the case front panel jack. — rfc, Mar 24 '22 at 20:32
Tried an answer, but then I saw that you actually get a sound but somehow broken. So one must assume your Audio USB is defect. Try to get a monitor with speakers. Maybe your HDMI card still works — kanehekili, Mar 24 '22 at 21:35
I only get a horrible sound from the mother board jack. I get nothing from the case front panel jack. Shouldn't both work properly and independently of the graphics card output? I don't have a monitor with speakers... — rfc, Mar 25 '22 at 00:42
yes, both should work, hence my assumption that your hardware is broken. You might try any live USB Linux just to doublecheck — kanehekili, Mar 25 '22 at 07:33
I dual-booted the computer and all jacks work on Windows (motherboard and case). So it seems that the hardware is fine. I also booted from a ubuntu stick and the motherboard jack work. The case front jack doesn't, though. — rfc, Mar 31 '22 at 13:30
You might need a driver for your board. I've got a msi and needed the nct6775 driver for my chips (including audio) Search for "linux drivers board ...." and replace the dots with your motherboard — kanehekili, Mar 31 '22 at 19:31
I have the same effect with Kernel 5.13.0-37 and also 5.13.0-39 but with Kernel 5.13.0-35 sound is perfect. Sorry I am not a Linux nerd having no idea about the reason. — Andreas, Mar 31 '22 at 23:04

One of the recent kernel updates seems to have introduced an issue with some audio devices. The solution is to modify PulseAudio’s default sample rate in daemon.conf.

Here’s how:

Open Terminal (if it’s not already open)
Open PulseAudio’s configuration file:
```
sudo {editor of choice} /etc/pulse/daemon.conf
```
^{Note: Be sure to replace {editor of choice} with your editor of choice.}
Find the line that looks like this:
```
; default-sample-rate = 44100
```
Change it to this:
```
default-sample-rate = 48000
```
^{Note: The preceding ; is gone. This is important.}
Save the file and exit
Restart PulseAudio:
```
systemctl --user restart pulseaudio
```

This should resolve your audio problems

appreciated but the problem occurs from different place. I confirmed my USB DAC works with 20.04.3 installer LIVE session and 22.04 Beta LTS without noises. Only this 20.04 LTS updates has a devil inside. – Sadaharu Wakisaka Apr 04 '22 at 08:36

The motherboard sound jack is working. Thank you! However, the motherboard mic jack is still not working. Neither are the jacks on the front of the computer case (sound and mic). Any hints on those? – rfc Apr 04 '22 at 18:13
While this fixes the ticking noise for me, this causes intermittent stuttering and audio stoppage. – stu177 Apr 14 '22 at 13:53
@matigo Does this affect audio quality in any way? – Mehdi Charife Jun 22 '23 at 08:51

I am not sure this is an answer or not. I tried these things and the noise is gone. (From Arch Pulseaudio manual)

Get rid of Timer based scheduler from sound server. Add tsched=0 to the udev module loader.

/etc/pulse/default.pa

load-module module-udev-detect tsched=0

Enable Echo/Noise-Cancellation

/etc/pulse/default.pa

Add this line

### Enable Echo/Noise-Cancellation load-module module-echo-cancel

Then kill pulseaudio and restart

pulseaudio -k
in case, you want to remove current settings mv .pulse .pulse_bak
pulseaudio --start

Perhaps this also was effective.
systemctl --user start pulseaudio.service

USB DAC plugged into another port and restart system.

Note: I do not know which one was actually worked.

After update from 18.02 to 20.02 ubuntu release, you have to restart the audio driver by using terminal

pulseaudio --start
