and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.
PR# kern/42028: hdaudio: mplayer can't change volume
Since the driver is not limited to OSS mixer APIs, allow for duplicate
mixer nodes with the same role. Resolves a regression where certain
controls may no longer be available that were previously possible with
azalia(4). Part of a fix for 42028. While here, add .mute controls to
address 42110.
implementation in that this code does not care if the headphones are seq=15.
Instead, for each association, find any HP pins with jack sense capabilities
and if at least one has the Presense Detect bit set, enable output on all
PWCs of type HP_OUT and disable output on all PWCs of type LINE_OUT, SPEAKER,
or AUX. Do the reverse if no HP pins have the Presense Detect bit set.
assume it supports 16-bit. This can be overridden completely by the widgets, so
some vendors don't specify a setting at the codec level. Fixes a panic in
this situation.
this is told by some "step" parameter read from the hardware
(fixes problems with a 5-bit register observed by Nicolas Joly and me)

It will replace azalia(4) after testing.
To use, comment out azalia in your kernel configuration and uncomment the
hdaudio and hdafg lines so it reads:
# Intel High Definition Audio
hdaudio* at pci? dev ? function ?
hdafg* at hdaudiobus?
You should also:
cd /dev
sh MAKEDEV audio
