Bug Description
Hello,
I have an integrated Intel ICH6 with AD1981B sound card on my laptop (HP Compaq nx8220). I usually use some speakers connected to the Headphone line out.
In Breezy, when using the Master Volume Control you could control everysound in the computer (internal speakers and headphones). In Dapper, this doesn't work anymore. So i need to low Headphone Volume control to quiet the external speakers.
I think the default behaviour should be the breezy one, so the master volume control everysound in the computer.
I am using Dapper up-to-date, with kernel 2.6.15-21-686
Hope this can be fixed before Dapper is released.

Please log out of GNOME and perform the following while logged in from a console.
1) Unload the snd_intel8x0 driver: sudo modprobe -r snd_intel8x0
2) Reload the snd_intel8x0 driver: sudo modprobe snd_intel8x0 ac97_quirk=hp_only
Please report whether passing the ac97_quirk=hp_only parameter to modprobe allows you to control the volume of the headphone jack properly. Morever, please attach (don't comment inline) the output from ``lspci -nv''.
