With PulseAudio 1.0, we added infrastructure to loosely support the concept of "ports", which are meant to be mapped to actual supported audio paths (read: physical outputs like your speaker or 3.5mm jack). These needed to be dealt with manually, and thus were not too interesting to users. With PulseAudio 2.0 and a recent Linux kernel (3.3.0 or higher), we now automatically detect whether a jack is plugged in to your device or not, and act accordingly. Currently, this buys us the ability to manage volumes for different outputs separately, and future work will allow more advanced features like easing the set up of multichannel output, etc.

Ah nifty. Unfortunately, I've been avoiding kernel 3.x until I can find out for sure whether it still supports my completely-open-source-friendly-but-old G400 that still runs fine (on its third motherboard). I heard a rumor they were dropping support, for some reason, but I hate to waste money replacing something that still seems to meet all my needs.

Ever considered that just building your own 3.x kernel and testing is a real cheap way to find out? Or grab a random LiveCD with it, and look?
(Sheesh)

Not sure I would have described the G400 (Matrox G400 right?) as open-source friendly. IIRC Matrox used to ship a black box binary that was needed to make various features work, without it you got a 2D framebuffer and some quality DACs, which aren't very relevant at this point because everybody is upgrading to digital video...
On my Fedora 16 box with 3.3.4, I seem to have a kernel module named 'mga' which claims to be for "Matrox G200/G400" and requires binary firmware I don't have (I probably have a G400 somewhere but no slot to put it in) but I
- don't know for sure that this works with your specific model (of course)
- don't know if it enables sufficient features to make a modern glitzy UI work properly, e.g. GNOME 3

Nope, I assure you, as a member of Debian, I did my research before buying this card, and it was one of the very few with full open-source support for 3d acceleration at the time. No blobs involved.
