Comment 4 for bug 381439

Yes AZaharia, I also tried to edit the /etc/modprobe.d/alsa-base.conf and it doesn't work either. But I cannot find the file /etc/modprobe.d/options , so im not sure about this modification. I just can find those files:

/etc/modprobe.d$ ls
alsa-base.conf blacklist-firewire.conf blacklist-oss.conf
alsa-base.conf~ blacklist-framebuffer.conf blacklist-watchdog.conf
blacklist-ath_pci.conf blacklist-local.conf dkms.conf
blacklist.conf blacklist-modem.conf libpisock9.conf

I also tried with many modifications like options snd-hda-intel model=m51va or options snd-hda-intel model=laptop but nothings happens.
