I am almost sure, I undid all the workarounds previously suggested in the comments (and Karmic Caveats), and with the attached pulse path the volume control is working fine. (both Master+LFE are equally affected first, then PCM) Alsa exports two analog volumes one for Master and one for LFE (this is usually called Master Mono) that controls the subwoofer. I think the confusion comes from the fact that if pulse controls the PCM (vía sink), it won't modify Master and LFE, but because it is an innermost volume in analog-output's path. Using the card this way fix to the max the two analog outputs and the volume range is shorter (only PCM). In addition, in my laptop if you set the volume of PCM to min, and the analog to max you still can hear noises. I think this is why there is a pulse path called "analog-output-lfe-on-mono", by the comments on the file, it is supposed to correctly support this setup, but it wasn't being available because it expects a Master Mono element, that it is being called LFE by alsa's mixer. It would be nice Daniel T Chen could take a look to this.
