Those hda codecs  with a single DAC (e.g. stac920x, alc260) and ad1986a
does no support independent headphone

Also those alc66x datasheet does not mention the support of multi-streaming
playback

Don't create the control when there is internal speaker

When driver assign two DAC to internal speaker and subwoofer (vt1802 on
Asus g75) and it is confusing when there is no headphone playback volume
control

Don't create the control when there is no headphone Jack  when the user is
retasked  the headphone Jack to Mic by early patching

Automatically disable for those headphone mic  jack when the HP Jack is
retasked as mic
