Hi there,
I have a problem where a USB audio device sometimes uses the soundcard slot 0 when connected during startup. This happens only from time to time with no obvious indication why it boots up differently.
I have set up /etc/modprobe.d/alsa-base.conf like this:
#autoloader aliases install sound-slot-0 /sbin/modprobe snd-card-0 install sound-slot-1 /sbin/modprobe snd-card-1 install sound-slot-2 /sbin/modprobe snd-card-2 install sound-slot-3 /sbin/modprobe snd-card-3 install sound-slot-4 /sbin/modprobe snd-card-4 install sound-slot-5 /sbin/modprobe snd-card-5 install sound-slot-6 /sbin/modprobe snd-card-6 install sound-slot-7 /sbin/modprobe snd-card-7
# Cause optional modules to be loaded above generic modules install snd /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbinmodprobe --quiet --use-blacklist snd-ioctl132 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } # Workaround at bug #499695 (reverted in Ubuntu see LP #319505) install snd-pcm /sbin/modprobe -- ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; } install snd-mixer /sbin/modprobe -- ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-mixer-oss ; : ; } install snd-seq /sbin/modprobe -- ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; /sbin/modprobe --quiet --use-blacklist snd-mixer-seq ; : ; } # install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; : ; } # Cause optional modules to be loaded above sound card driver modules install snd-emu10k1 /sbin/mod ..... ..... # Prevent abnormal drivers from grabbing index 0 options bt87x indes -2 options cx88_alsa index ...... ..... # Keep snd-usb-audio from being loaded as first sound card options snd-usb-audio index=-2
alias snd-card-0 snd-hda-intel alias snd-card-1 snd_hda_codec_atihdmi alias snd-card-2 snd-usb-audio alias snd-card-3 snd-usb-audio alias snd-card-4 snd-usb-audio alias snd-card-5 snd-usb-audio alias snd-card-6 snd-usb-audio alias snd-card-7 snd-usb-audio
options snd-hda-intel model=6stack-digout options snd-hda-intel index=0 options snd_hda_codec_atihdmi index=1
options snd-usb-audio index=2,3,4,5 id=midi1,midi2,midi3,midi4
Does anybody have an idea why the USB keyboard still takes over the sound card slot 0 and keeps the sound-card from showing up? I just took a look at /sbin/. "modprobe" links to /bin/kmod. Are there any other setup files for the sound cards other than /etc/modprobe.d/alsa-base.conf?
When I edit and store alsa-base.conf in the console it tells me [MAC-Format] by default. Should this be set to [DOS-Format] in order to be readable?
Any help or ideas are appreciated!
Thanks! Ingo
