Sound Issue in Fedora 8

Today I upgraded my system from Fedora 7 to Fedora 8. The installation process went very smoothly. But once the installation was done, I started the long process of configuring it. That’s when I ran into the sound issue in Fedora 8 – and based on the forum posts, so did many others.

Basically, you get this error at KDE startup…

Sound Error Informational Message:
Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
The sound server will continue, using the null output device

You will not be able to play any sound – amarok will crash if you try to play anything. But if you run system-config-soundcard(or System -> Administration -> Soundcard Detection), you will be able to hear the test sound. That is because you are running it as root.

Solution 1 – Console-Kit Service

Did you turn of Console-Kit and avahi-daemon startup services using system-config-services? If so, go back and re-enable them.

  • Run system-config-services(or System -> Administration -> Services)
  • Find Console-Kit and enable it
  • Find avahi-daemon, enable it
  • Restart the system and see if that fixed the problem.

This worked for me – so I did not try any of the following solutions.

Solution 2 – alsa-plugin

If the first solution did not solve the problem, try removing the pulseaudio plugin for alsa by running this command.

yum remove alsa-plugins-pulseaudio

Solution 3 – Permissions

If neither of the above work, open /etc/security/console.perms.d/50-default-perms and add this line to the top…

<sound>=/dev/dsp* /dev/snd/*

And at the end, add this line…

<console> 0666 <sound> 0600 root
