Fedora 11 KDE 64 bit
External USB audio: Creative SB Live! 24 bit
64 bit beta flash plugin
External sound card is configured as first preference in System settings > Multimedia, and is shown as recognized and active.
Nevertheless, the sound card works very patchily with flash content such as Youtube. Sometimes repeated switchings off/on and disconnects/reconnects help, sometimes (like now) not. I also tried the 32bit flash-plugin, with no different results.
Has anyone else run into a similar problem and found a solution? It seems like it might be to do with KDE 4.2, since it's present over on OpenSUSE 11.1 with KDE 4.2 installed, whereas there are no problems in Fedora 11 Gnome.
