Audigy LS / ALSA Volume control
Hi,
I recently bought a new computer and installed Debian unstable for amd64 on it. I'm having trouble with my Creative Soundblaster Audigy LS card.
I am trying to use ALSA with my card and the ca0106 module. I get sound from the card, but the sound is really loud and I have to have my volume setting at the lowest possible value in alsamixer (or Gnome ALSA mixer) and the sound still almost "breaks".
I have tried all the plugs in the sound card and I have the right one as it is the only one that works and it is color coded green. I'm using the analog out and the card doesn't even have SPDIF, even though ALSA offers SPDIF controls in the mixer.
I'm able to adjust the volume with a hardware stereo system, but it would really help if I could get the volume that comes out of the computer down to normal line out levels.
Here is the ALSA configuration file from my system:

------------------
I must say that the meaning of some the "controls" is still somewhat vague to me, even though I have tried to read all the documentation I have found.
Thanks a lot for any help,
