To make ALSA show the proper controls for my sound card I had to tell it which model I'm using /etc/modprobe.d/modprobe.conf: options snd-hda-intel model=6stack-dig Look in /usr/src/linux/Documentation/sound/alsa/HD-Audio-Models.txt to see the list of models. Hopefully then it will show things appropriate to yours.
