Take a look here: petter@monster:/etc$ lsmod | head Module Size Used by nls_utf8 16384 0 ufs 77824 0 qnx4 16384 0 hfsplus 106496 0 hfs 57344 0 minix 36864 0 ntfs 102400 0 msdos 20480 0 jfs 188416 0 The first row is the name of the kernel module. As you can see, the second is size, and in this example there is nothing under "Used by" except zeroes. The zero means that no other modules depend on this one. If there had been dependent modules, this row would list the number of dependants, and then a complete list of them. You can then use this information to track which modules are needed for a specific module to load. Like this: Module Size Used by snd_timer 32768 2 snd_pcm,snd_seq This means that there are two modules that depend on snd-timer - snd-pcm and snd-seq. snd-timer then have to be loaded first before either of those can be loaded. You can then backtrack through the lsmod output to see what other modules snd-timer depend on (by grep'ing for it), for instance, and thus see the entire chain of modules that are required for any specific module to function. All of this should be handled automatically, but there are occasions when a module needs to be force-loaded. Is that any clearer? I can't explain it any better in English, and I expect an explanation in Norwegian wouldn't help you very much :) In regards to your problem, I really don't know why snd-hda-intel won't load automatically for you. It might have to do with recognition of your hardware, that it isn't probed correctly or something. The easy solution is probably to just add "modprobe snd-hda-intel" to /etc/rc.local and leave it at that. If you really want to follow up on it, you would need to grab the details of your sound hardware from lspci and do a few web searches. If nothing comes up, then file a bug report.
