I'm running Firefox with Xvfb on a Linux server (CentOS 5.4). I alspo have the Flash plugin loaded, but it does not work because I do not have a sound card: $ alsamixer alsamixer: function snd_ctl_open failed for default: No such file or directory

It is possible to create a fake sound card on the server?

Why do you need to view Flash on a server? Why do you even have a GUI on a server? – John Gardeniers Aug 3 '10 at 10:10

It could be as easy as enabling snd-dummy kernel module, which fakes a sound card.

Try modprobe snd-dummy and if that helps, you might want to add snd-dummy to your /etc/modules.conf or wherever CentOS wants default modules added; might also be under /etc/modprobe.d.
