Looks that mute bits in mixer paths for CS4231 - and possible with other
hardware - turn off complete specified path. If you leave volume at
minimum value and analog path is unmuted, some analog signal (very loud)
still comes from this path.

I still think that best way for card initialization is disable all paths
until user doesn't enable only selected. All paths in analog mixers should
generate noise and some default settings can't be good for all users
(there is problem mainly with some generic drivers like AudioDrive
ES1688 which covers many clones which should have different amplifiers).
