Pulse sound server questions

I seem to have lost connection from alsa to the pulse sound, I can hear white
noise when sliding the volume controle but no sound in applications nor CD playback.
I did do some applicatin installing from the control center bu having installed
more than one at a time I have no way of knowing if an application busted things.
I didn't add anything concerning sound that I recall.
I get no error messages.
Anyone have a clue as to what may have happened?
TIA - Ken

Are you perhaps running KDE4 on a 64-bit machine?

I lost sound some days ago, under KDE4, KDE3 and GNOME desktops,
2009.1 with all updates. I suspect an update broke something.
I have dropped back to 2008.1 for this and other reasons, so I
have not tried to track out the problem in any great detail.

Going through the trouble-shooting instructions found under
Configure you sound system in MCC provides nothing useful.  All
seems ok.

When started from within a terminal window under KDE3 I got an
error message about multithreading not being supported when I
started Amarok.  No error message for juk, rhythmbox, or
audacious, and the status bar would show progress but no sound.

Under 2008.1 (using arts, not pulseaudio) I have no problems, so
I assume it is not the sound card.

Cheers!
