Ok, that makes some sense. It translates to me as
- With independent HP turned off - activates auto-mute between
speaker-out/line-out and headphone out. Note the difference between VIA and Realtek/Sigmatel here as line-out are auto-muted as well.
The point is using ac97 front panel connector does not allow you to know whether the headphone plugged in , the presence of headphone is only know when you are using HDA front panel and HDA codec. so line-out of a desktop is usually not auto muted
