There are some restrictions for automatic parser. The STAC/IDT parser supports dual headphones, but realtek one doesn't, so far. But, anyway 3 headphones are wrong. Note that by setting the pins to HP, you get the amp boost in the codec chip, but it doesn't mean it's better audio quality. For line-outs, you shouldn't put such an amp usually.
