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 ;)
At least on Gentoo it is /etc/modprobe.d/blacklist.conf (the actual path and/or
filename may vary on different distros). Put a line containing 'blacklist
snd_hda_intel' or some other kernel module on it.
Device 2 uses snd_usb_audio-module so by blacklisting it you lose all
USB-audio-devices. As for the admittedly stupid HDMI device (3), on current
kernels it comes hand-to-hand with snd_hda_intel, so you can't have the one
without the other.
