Uninstalled flash, reinstalled, searched numerous threads about flash problems, made the HDMI device the first priority, still nothing.
Slackware 13.37 had the same problem and the solution there was to create ~/.asoundrc:
Didn't work in Fedora.
One command as root fixed it, and noting else was adjusted.
yum groupinstall 'GNOME Desktop Environment'
Now sound works fine in the browser in both Gnome and KDE.
I have similar problems with my sound in GNOME on Fedora 15. This is not the case with KDE on the same system.
I've just executed the command (in my home system over OpenVPN) as root but can't confirm now if it works or not because I'm still at the office. It hope it does work and I'm be back here to confirm it. Meanwhile, thanks for your contribution.
