Look, I don't have a proper opinion on how the keys are achieved ...

all I want is that the sound driver is:

1/ called through the standard ioctl() for volume - however many "volumes"
you want to adjust.

This is so that *your* interface will work with *any* dmasound-supported
hardware (without hacking dmasound for each chipset).

We currently support 3 1/2 chipsets - with two more in the pipeline + Apple
is releasing sound hardware variants faster than we can keep up with the
driver already ;-))

also think about how it might interact with USB audio ...

you ***really*** ***don't*** want to go down the road of hacking every sound
driver for volume keys.


2/ Let dmasound handle the headphone insertion - it is already dealing with
the hardware and the appropriate interrupts.

By all means - if there is a consensus that we *need* User Control over
whether headphone insertion disables the internal speaker (or not) - then I
am happy to use one of the OSS "special purpose" ioctl() values to control
this as a PMac-specific feature - which will work properly via the proper
ioctl().

just my 0.02 euro ...

but I am (at least unofficially) maintaining the driver at the moment.

ciao,
Iain.
