Can't play sound in Kubuntu 12.04

I just installed Kubuntu 12.04 on my computer, and I can't play sound when viewing YouTube videos. Any suggestions? Thanks!

Sometimes the playback device is muted by default. (I never understand why that would be, but it does seem to happen sometimes on Kubuntu.) To fix this problem, you need to run "sudo apt-get install pavucontrol" then run the pavucontrol program from a terminal or by pressing Alt-F2 and typing "pavucontrol" in the box that appears. Look through the tabs and see if either the input or output device is muted. You can tell by whether the little mute icon appears depressed or not.

Hope that helps.

That worked! I went to the "playback" tab, and changed the ALSA plug setting from Built-in Audio Analog Stereo to SB Audigy Analog Stereo. Thanks!

If that was the issue, and not muting, you should look at System Settings > Multimedia > Phonon. That lets you select the audio device to be used for a variety of different situations.
