I am facing audio problems on kubuntu 14.04.

I have already removed the fast boot from windows 8. So, That can't be the problem.

I was trying this: https://help.ubuntu.com/community/SoundTroubleshooting

paacmd shows that the device is not muted.

Here, "aplay /usr/share/sounds/alsa/Front_Center.wav" doesnt work for the user.

Even in the admin am getting error

subodh@Arya-XPS:~$ sudo -i
root@Arya-XPS:~# sudo aplay /usr/share/sounds/alsa/Front_Center.wav
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
aplay: main:722: audio open error: No such file or directory

Once I had tried this command to get the audio working:

rm -r ~/.config/pulse; pulseaudio -k

now it is no longer working.

So it is a configuration problem on kubuntu?

  • When did sound problem occur, did it work when you installed Kubuntu – Faizan Akram Dar Mar 4 '15 at 6:07
  • When i kubuntu installed it was not working. Then I read somewhere to try this : rm -r ~/.config/pulse; pulseaudio -k. this issue was also intermitent on windows. So i install the windows audio driver from dell support. After that it stopped working on kubuntu. – subodh1989 Mar 4 '15 at 6:09
  • try reinstalling pulseaudio by executing following command in terminal: sudo apt-get install --reinstall pulseaudio – Faizan Akram Dar Mar 4 '15 at 6:10
  • tried that not working – subodh1989 Mar 4 '15 at 6:17
  • please edit your question with output of command lspci -v and content of /etc/modprobe.d/alsa-base.conf – Faizan Akram Dar Mar 4 '15 at 6:44

First Method:

Execute following commands one by one in terminal :

sudo apt-get remove --purge alsa-base pulseaudio

sudo apt-get install alsa-base pulseaudio

sudo alsa force-reload

Restart your system and see if sound works.

Second Method:

Open the terminal and edit speech-dispatcher file by using the following command:

sudo gedit /etc/default/speech-dispatcher

and change RUN=yes to RUN=no

Restart your system and see if it works.

If none of above works, try editing alsa-base.conf by following method:

Execute following commands in terminal

sudo gedit /etc/modprobe.d/alsa-base.conf

and add this line to the file and save it, then reboot your system.

options snd-hda-intel model=auto
  • the first and third command doesnt work. – subodh1989 Mar 4 '15 at 16:45
  • For the second command file does not exist . I have checked in other system having kubuntu. It doesnt need that file. – subodh1989 Mar 4 '15 at 16:46
