Like my previous speaker already told: the modules cannot be loaded because other modules are missing. Either you don't have modules installed at all (which most certainly means you have a wrong kernel image running) or the module loader cannot resolve the dependencies. To check if the module directory exists type $ ls /lib/modules/$(uname -r) and check if a directory listing is displayed or an error indicating "directory not found". If it exists, try $ sudo depmod -a before modprobe to make the module loader know the missing modules that have to be loaded automatically. ---- On Sat, 12 Feb 2011 17:26:13 +0100 James Shatto wrote ---- >As I suspected, the modules aren't loaded so alsa isn't even running. >Hence your original "open" error(s). > >How did you install alsa?
