Here's the section from GENERIC on 11.1 for sound (it's the same for 10.4 and 12-CURRENT): # Sound support device sound # Generic sound driver (required) device snd_cmi # CMedia CMI8338/CMI8738 device snd_csa # Crystal Semiconductor CS461x/428x device snd_emu10kx # Creative SoundBlaster Live! and Audigy device snd_es137x # Ensoniq AudioPCI ES137x device snd_hda # Intel High Definition Audio device snd_ich # Intel, NVidia and other ICH AC'97 Audio device snd_via8233 # VIA VT8233x Audio So you need to add nodevice entries for all the ones that you are missing (snd_cmi, snd_cma, snd_emu10kx). Always check the kernel config file you are including to see what you need to exclude via nodevice. :) -- Freddie Cash fjwcash@gmail.comhelp
