No sound

[Kr1551]

Yesterday I had put last lts version of Ubuntu on my laptop and the sound did not work, only with headphones did it work. now I just booted lubuntu. No sound, not even with headphones.

Can someone help me out?

Go to sound preference to see if the hardware is in order.

Go to sound preference.

In preferences, I can't find anything related too sound or audio.

It's like the audio is not installed or something stupid.

You can try removing and reinstalling ALSA and see if it automagically finds your cards from a clean state.


(1) Remove the ALSA packages
Code:

sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

(2) Reinstall the same packages
Code:

sudo apt-get install linux-sound-base alsa-base alsa-utils

Packages gdm and ubuntu-desktop are also removed in this process if you are using Gnome. They need to be reinstalled:
Code:

sudo apt-get install gdm ubuntu-desktop

(3) Reboot

This work for me.

I'm having a similar issue after an update last week.

It appears to be a pulse audio issue based on running the following from the terminal:

tail /var/log/syslog

kernel: [  138.172355] pulseaudio[3058]: segfault at 1b86 ip 0000000000001b86 sp 00007fffbac590d8 error 14 in pulseaudio[400000+13000]

So how can I get my sound?

Ditto with the sound problem. It appears it detects my devices, and I hear pops and clicks occasionally, but otherwise nothing. Reinstalling alsa didn't help, and I'm really close to ditching Ubuntu.
