Hi,
The speaker output of my DELL laptop D430 doesn't work, I have sound only by the speaker of my laptop. It is impossible to desactive Intel sound card by the bios. I bought a usb sound card Terratec. I always have a sound on the speaker of my laptob but no sound on output of usb sound card. I think there is a conflit between Intel sound card and usb sound card. This is a file alsa-base.conf : # 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 && { /sbin/modprobe --quiet snd-ioctl32 ; /sbin/modprobe --quiet snd-seq ; : ; } install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --quiet snd-seq-midi ; : ; } install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 && { /sbin/modprobe --quiet snd-emu10k1-synth ; : ; } # Keep snd-pcsp from beeing loaded as first soundcard #options snd-pcsp index=-2 Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 # Prevent abnormal drivers from grabbing index 0 options bt87x index=-2 options cx88_alsa index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 This a file alsa-base-blacklist.conf # Uncomment these entries in order to blacklist unwanted modem drivers # blacklist snd-atiixp-modem # blacklist snd-intel8x0m # blacklist snd-via82xx-modem # Comment this entry in order to load snd-pcsp driver blacklist snd-pcsp Thank you for your help.
