How do I reset my Audi audio system?

I was listening to music, and my sound suddenly went dead in all my applications. I’m using Ubuntu 12.04, which uses pulseaudio, so I tried sudo /etc/init.d/pulseaudio restart , but nothing happened. According to lsof | grep pcm , nothing is using the soundcard at the moment, although I’m not entirely sure if my source for that command is applicable. Is there a way another way to restart Ubuntu 12.04’s sound system from the command line without rebooting the system?

I think the solution really depends on the computer you have and the ubuntu version installed on it. For me none of the 2 top answers worked. joeytwiddle’s answer worked. já mám Lenovo Legion Y520 s ubuntu 16.04: sudo pm-suspend is the only thing that worked for me.

This is NOT an answer to the question, however, this page show up in the top when searching for how to fix the sound in Ubuntu 18 and 19. When having trouble with the motherboard built-in Intel soundcard, this solution has worked for me: linuxuprising.com/2018/06/… Excerpt: Ubuntu 18: add «options snd-hda-intel model=generic» at the end of the /etc/modprobe.d/alsa-base.conf reboot Ubuntu 18, 19, 20. Kernel 5.3.0-41 and -42: Edit /etc/modprobe.d/alsa-base.conf as root and add «options snd-hda-intel dmic_detect=0» Edit /etc/modprobe.d/blacklist.c

I’ve used pulseaudio -k && sudo alsa force-reload a couple of times, and it worked well. The first part kills pulseaudio, the second reloads ALSA. You don’t need to restart pulseaudio, because it auto-restarts.

This helped to me to fix the issue ‘no sound after suspend’ I have suffered from for don’t remember how long.

Sometimes you might need to clear pulse config with «rm -R ~/.pulse*» before issuing any restart.
23. září 2014 ve 11:33
It works for me after my USB headphone stop to work.

What I do when my sound doesn’t work is

killall pulseaudio

and then I press Alt + F2 and type in pulseaudio. It usually works for me.

What is the difference between this and systemctl —user restart pulseaudio ? The restart worked for me before, but today it did not and I needed to kill it (it seemed to automatically restart, when I typed pulseaudio in a terminal it errored that the daemon is already running).

23. září 2021 ve 12:32

There isn’t much difference in practice. This answer relies on systemd detecting that pulseaudio has crashed and restarting it. Your version does this explicitly.

Just for completeness, in newer Ubuntus versions that use systemd, I used this and it worked well:

systemctl —user restart pulseaudio

This is the way to restart PulseAudio in Ubuntu 20. Thank you!
1. listopadu 2020 ve 19:43

This, along with killing/restarting Alsa, allowed me to get the audio working on my Acer Swift 3 (Ryzen 4700U) under Kubuntu 20.10.

12. listopadu 2020 ve 4:46

This answer is very useful since pulseaudio won’t function properly after a session change (or CTRL-ALT-BACKSPACE) in ubuntu 20.04

3. června 2021 ve 14:13
still works in 2023 with an up-to date ubuntu

In my case there were nasty messages in kern.log / dmesg :

sound hdaudioC0D2: HDMI: invalid ELD buf size -1

The solution was simply to suspend and resume the machine!

$ sudo pm-suspend

i don’t know what was going on, I also had a mike problem, reinstalled pulseaudio and alsa packages, but the sudo pm-suspend trick did it.

Same thing happened here — after battery died, headphones did not work after next boot. pm-suspend fixed it.

For the new multimedia framework Potrubní vedení, which became the default since Ubuntu 22.10, restart the Pipewire services.

❯ systemctl --user restart pipewire.service # if the above is not enough, try ❯ systemctl --user restart pipewire-pulse.service

@s.ouchene Thanks, it shouldn’t be a «newer version» I have rephrased it.

I had exactly the same symptom: sound suddenly died (after trying to use Audacity, in my case). The OP didn’t mention he was/wasn’t wearing headphones, which was my case. I tried all options here and, when going to Preferences and changing to HDMI or Speaker output worked, but switching to Headphones didn’t work (no sound). I then tried to unplug and re-plug the headphones and it worked.

I encountered this issue with a USB audio device that would sometimes when booting the machine, not connect properly leaving me without audio until a reboot. If you are someone who is having the same issue but with a USB audio device then I recommend the following which fixed it for me:

sudo rmmod xhci_pci && sudo rmmod xhci_hcd && sudo modprobe xhci_pci xhci_hcd

None of the other answers would fix it and I assume that came down to the USB device not registering properly on boot. This simply reboots the USB devices. Note: you should only run all commands at once, running sudo rmmod xhci_hcd alone will disable all USB devices e.g., your keyboard, meaning the remaining commands cannot be run.

I will be honest and say that I doubt that the xchi_pci part is necessary, so if someone is more knowledgeable regarding this please correct me.

STEPHEN říká:

Dobrý den,
I had a liquid spill on my MMI control panel (A6 Avant 2008). Over time all the buttons ceased to work but I could still control it from the steering wheel. Every so often the control panel would light up and some buttons would work but very rarely. I’m guessing that one of these times I accidentally hit the off button and then had no way of turning the system back on. I managed to take the centre console apart and open the control panel. The circuit board was pretty sticky but I gave it a good clean and everything bar one function works now. Unfortunately the one thing not working is the centre knob/wheel. The press down button on the function of the knob works fine but when I turn it, it doesn’t scroll through the options like it should. When I have the face off I can control the censors on the circuit board with my finger but when I put the face back on and trythe knob for real I get nothing. Could you please give me some advice or trouble shooting tips. I thought about resetting the system but didn’t know if that would work also I was worried that I would lose all my programmed stations and have no way of retuning because the knob isn’t working (I’m guessing that a reset clears all tuned stations?).
