Sound in Ubuntu Hoary Hedgehog – Part 1

Problem
Sound works for some applications in Ubuntu 5.04 (Hoary Hedgehog), but fails for others. For example, rhythmbox and xine can produce sound, but the Flash plugin for Firefox doesn’t.
Solution
  • Close any applications that are trying to access sound. This includes any browsers, because they have plugins like Flash running.
  • At the command line, kill the ESD daemon: killall esd
  • Set your sound preferences (System > Preferences > Multimedia Systems Selector) to ALSA or OSS (ALSA works better for me).
Explanation
ESD has trouble sharing, apparently. Killing it works as a stop-gap measure if you need to play just a few things. I’ll search for a better solution.
