I have a toshiba tecra A6. It contains a Realtek ALC861 based soundcard.

I have two major problems with this card. First off, no software mixers actually properly control it. Secondly, the output is far far too quiet. Its at the point that any speakers I plug in have to be cranked to max volume just so I can listen as quiet listening levels.

And the output of
sudo /etc/init.d/alsa-utils restart results in

I have added 'options snd-hda-intel model=auto' to '/etc/modprobe.d/alsa-base' which fixed some errors. model=toshiba results in even quieter sound.

If anyone has a realtek alc861 soundcard and worked through similar problems, your experiences would be wonderful.

Any ideas?
