Summary:                    LFE Volumne Control & Mute/Unmute not working
Description: 
if try to set lfe volume or unmute lfe control with alsamixer or amixer, my
changes always will be reverted and so i never geht any lfe output. if
have an aopen i915GM-HFS motherboard and use alsa kernel from 2005-07-12
(nitro5 kernel).

also capture volumne seems to work not ok. i have set it 11 percent. it's
the maxmium for me. higher values produces oddly noises.

Thanks, I fixed it on CVS in a bit different way.
(Also the callback for volume had to be fixed.)
