have you try the model=6stack-digout or 6stack-automute ?

HP in ALC880_FIXUP_6ST_BASE explicitly disable jack detection ,

Do you need a new model which support headphone automute speaker with digital output since 6stack-automute does not have digital ouput ?

Do you mean the driver still does not provide any warning message when all your pins are ignored by the driver ?
