I'm using Fedora 11 right now (trying to switch permanently to Linux)
one of the thing i'm having problem with is the Digital Sound
the system can see the device but, noting coming out of the speakers
my sound card info (using alsascript) is: here
some how it's start working ...
i tried this command
$ mplayer -ao alsa:device=hw=0.4 test.avi
and now it's working as default in vlc as well
