It's difficult to confirm what happens with the beep under Intel HD Audio. Intel's reference documentation for HD Audio only mentions "beep" in reference to volume within the ICH7 (AC97) register. The ICH7 documentation only states that it supports passive speaker connections for ACZ_RST#. Based on that small amount of information, I assume its up to individual motherboard designers how or if they implement PC Speaker.
