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, 2022 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, 2022 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, 2022 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, 2022 at 0:42
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, 2022 at 7:33

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.

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?

While this fixes the ticking noise for me, this causes intermittent stuttering and audio stoppage.

Try this

sudo apt-get remove --purge alsa-base
sudo apt-get remove --purge pulseaudio
sudo apt-get install alsa-base
sudo apt-get install pulseaudio
sudo alsa force-reload
sudo reboot

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.

Downgrading to 5.13.0-35 fixed popping noise with XRUN on JACK from USB interface.

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

pulseaudio --start
