PulseAudio uses up a lot of processing when I open up a video on YouTube or play something on Rhythmbox. The YouTube video never loads, and the music on Rhythmbox starts skipping like a minute every second.

I tried sudo killall pulseaudio then running pulseaudio logged in as root. I get the below error messages after a little bit:

root@aa-ul:~$ pulseaudio
W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).
W: [pulseaudio] alsa-mixer.c: Your kernel driver is broken: it reports a volume range from 0 to 0 which makes no sense.
W: [pulseaudio] alsa-mixer.c: Your kernel driver is broken: it reports a volume range from 0 to 0 which makes no sense.

Here's a link to the output of pulseaudio -v that I killed when it took a while.

Output of aplay -l:

aa@aa-ul:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****

  Subdevice #0: subdevice #0
card 2: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]

How can I get audio to work? I tried apt-get install --reinstall pulseaudio but it didn't work.

I'm running Ubuntu 14.04 64-bit over 3.13.0-34-generic, and the system is up-to-date.

Here's the output of an ALSA information script that contains the output of some useful commands: http://www.alsa-project.org/db/?f=d43a5b6bca9e599edad228c9c34f3f46987214be

  • I found the solution in this question: How to reinstall PulseAudio (Ubuntu 12.04). I removed pulseaudio, ran rm -r ~/.config/pulse, reinstalled pulseaudio, ran sudo alsa force-reload and restarted. Note: removing pulseaudio removed ubuntu-desktop, so I also installed it when reinstalling pulseaudio. Anyone facing this issue could probably try removing the ~/.config/pulse only and restarting. – Alaa Ali Aug 24 '14 at 20:54
  • "Your kernel driver is broken" suggests a problem with the kernel; what one are you using? – lyra Aug 24 '14 at 20:31
  • 3.13.0-34-generic. I've added extra information to the question. – Alaa Ali Aug 24 '14 at 20:35
  • Did you try updating? I'm already using 3.13.0-35-generic, uname -r says, which means there's a newer one out. – lyra Aug 24 '14 at 20:37
  • Yup, everything is up to date, which repositories are you using? – Alaa Ali Aug 24 '14 at 20:45
