OK, so I just had a chance to test on an FC4 box, and indeed, just
changing the gstreamer-properties (or under Preferences -> More
Preferences -> Multimedia Systems Selector) so that the Audio output was
ESD and the Audio input was OSS did the trick!  (I'm using esd on the
thin clients).  Sound came out as expected when I test the Audio Output
ESD test button.

(BTW:  For video to work properly on most thin clients, change the Video
Output under the Video tab to "Xwindows (No xv)")

Now, this wrote a configuration file in my user account, so this doesn't
seem to be system-wide.  The conf file is

There is a corresponding file in /etc/gconf/gconf.xml.defaults , but I'm
not sure exactly how to edit it.  I'll let you know once I google around
a bit.

Anyhow, since gstreamer is used for gnome and kde these days, this
should fix sound for most applications.

Now, if you use nasd....  I would try setting the Audio output to OSS,
but I'm an ESD kind of guy, so I'll leave that to the nasd fans...

Hope that helped,
