HP nx6110 quirks

The HP nx6110 laptop needs to have Headphone Jack Sense enabled so that the internal speakers will be turned off when headphones are plugged in.

Also ac97_quirk=hp_only is needed to make a single Master volume in the mixer instead of separate volumes for internal speakers and headphones, which just confuses the user.

The patch is for the current alsa-kernel CVS.

The ALSA driver is supposed to expose all the hardware functionality. It's up to the mixer apps to present it to the user in a sane way. So if the hardware supports separate volume controls for the headphones and internal speakers we should not disable this functionality. Why not make three controls, Master, External Speakers and Headphones?

Then we will need to create virtual controls - the chip has only two volume control registers for this, so we will need to make three virtual controls for volumes, then combine values and write them to the chip. And this will need to be done inside the driver (otherwise where the values of virtual controls will be stored while no ALSA programs are running?). Would this be acceptable?

Actually I was wrong, this is actually supposed to be handled by the new abstract mixer layer in alsa-lib. You're right, it does not make sense to make each mixer implement it.

I don't think it's well documented yet but AFAIK it should work.

Thanks, applied to CVS.
