maestro3 hardware volume control

[Panagiotis Astithas]

Weird, on my HP Omnibook XE3, the on-board maestro3 has been working 
flawlessly all along without any entry in /boot/device.hints. If I add:
hint.pcm.0.hwvol_config="0"
then the hardware volume controls on the laptop stop functioning. 
Setting it to "1" makes it working again.

Does that mean that GPIO pin 4,5 was selected as the default by some 
other means on my system? Could ACPI be doing it?


Cheers,
