<pre>
for those hda codecs which have ac97 like analog mixer (e.g. ad1986a,
vt1708,...)
the alsa driver already removed the corresponding "PCM" playback volume and
playback switch when those codec use hda_generic.c to create the controls
it use set volume to 0dB and unmute without creating any control
the remaing hda codecs are those without analog mixer need change of control
name to indicate whether it is shared by two or more ports
