At one point my sound was working just fine in KDE (so I know this isn't a hardware problem), but then I decided to give gnome a try. I couldn't get sound to work on gnome so I tried installing a new version of xmms and its plugins. I couldn't get it to work so I tried to undo everything that I did and then went back to KDE.
Now my sound won't work. In fact, xmms will hang unresponsively when I play anything. My web browsers with flash plugins (mozilla_1.1 and netscape_x.x) also hang at certain websites--I think this is because they are trying to play sounds. I can, however, play audio CDs -- I think this is because they don't go through the software, right?
When I turned up the verbosity of arts to "informative," I get the following two messages at startup:
file format extension kde/share/sounds/ unsupported
Can't set real-time scheduling priority.
You need to run artswrapper as root or
setuid root. This means that you will
likely not be able to produce acceptable
sound (i.e. without clicks and breaks).
I tried doing what the second one said, but it didn't help. Does anyone know what might be going on?
