I hope they'll be in PulseAudio 2.0, as they are currently waiting for
review. For next release, see , but judging from the PulseAudio 1.0
release process - no, I don't know when this will be ;-)

If you want them to apply to PulseAudio 1.1, you can have a look at .
The patches currently posted apply to git head. You'll need all of the
06* patches (as well as Linux 3.3 for the kcontrols).
A more light-weight version could be what I did in Ubuntu 11.04, where
there was no jack detection, but I just exposed all four devices in
PulseAudio and let the user choose manually, like this . (I later
renamed that file from "nvidia.conf" to "extra-hdmi.conf", and added the
same file to be used for Intel chips.)

Certainly, if there is interest from the Debian side to have it.
I would also not mind if it became a part of upstream ALSA, I think it
would make a nice addition to the hda-analyzer, hda-verb etc tool set.

I think the easiest way is just to download the hda-jack-retask
application and build it yourself. Otherwise, .
