[LAU] Blacklisting undesired audio devices

Hi folks, I'm wanting to blacklist some audio devices so that the drivers don't get loaded on boot. avl5@funkster1:~$ cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe8f0000 irq 16 1 [M1010LT ]: ICE1712 - M Audio Delta 1010LT M Audio Delta 1010LT at 0xe800, irq 20 2 [U0x46d0x8ce ]: USB-Audio - USB Device 0x46d:0x8ce USB Device 0x46d:0x8ce at usb-0000:00:12.2-2, high speed 3 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfe9ec000 irq 44 4 [BCR2000 ]: USB-Audio - BCR2000 BEHRINGER BCR2000 at usb-0000:00:12.1-1, full speed 5 [DR880 ]: USB-Audio - DR-880 BOSS DR-880 at usb-0000:00:12.0-1, full speed I want to blacklist 2 + 3 (webcam and RADEON HD4650 HDMI). I'm using AVLinux 5 (debian 6.0.1) with the custom pae_kernel 2.6.39-2 and after reading the alsa website for the correct ordering of cards on boot, I learned that we should use the 'slots' option instead of 'index=nn'. The appropriate line in /etc/modprobe.d/alsa-base.conf is now: options snd slots=snd-hda-intel,snd-ice1712 But I couldn't find anything about blacklisting. Mybe I'm just to blind to see. :( So if anybody could help me out, I'd be very grateful. TIA, Raphael ;)
