Hi again-
Having fooled with the Pi a few more hours I think I now have a better idea how the thing behaves.
The main difficulty I've had is that having a USB keyboard and/or mouse connected to the Pi seems to conflict with USB audio devices. The main symptom is that Pd's GUI freezes. This seems to happen whether the GUI is running on the Pi's own X server or over an ssh connection.
The best mileage I can get is to ssh over from another machine, so that the only USB devices on the pi itself are the audio device and the network adapter (which is implemented as a USB 2.0 device.) I'm suspicious that the addition of a keyboard forces USB down to 1.1, but things break even if I plug in a keyboard via a USB 2.0 hub. (It's an old hub though, maybe a newer one would work better?)
I was then able to get audio output going with only occasional glitches (3 or 4 per minute I think.) I was never able to get input and output both working at once without manifold glitches.
I'm using Pd 0.44 (test version) for this, which I've just fixed up to not require the tcl and tk h files to compile Pd (why I didn't clean that out earlier I have no idea :) It's still necessary to run:
apt-get install libasound2-dev
before Pd wil be able to use the ALSA audio. Then grab Pd from git:
git clone git://pure-data.git.sourceforge.net/gitroot/pure-data/pure-data
(Maybe you'll have to apt-get install git first), then cd to pd/src, ./configure and make. Takes about 17 minutes to compile.
And by the way, don't use OSS audio - it's not running by default but if youturn it on and try it out; it instantly crashes the Pi.
WHAT I DON"T KNOW YET: I don't have an HDMI monitor and so can't test the "HDMI audio". I imagine it might be more robust than using USB audio device (and, by the way, in 0.44 you can sort of get away with using separaate devices for input and output, although there's no correction for clock drift).

There are adapter cables designed for the XBox that extract stereo audio from the HDMI stream. That might work for the Pi. BestBuy and Fry's have them. Looks like this:

Hi Miller,
It's very good news you took a closer look on how Pd behaves on the Pi ! What distro are you using ? The standard Raspbian wheezy, or something else?
Cheers,
Pierre.

I've got out-of-the-box Raspian (2012-08-16-wheezy-raspbian.img). I stuck it on an 8G SD card and my first nice surprise was that it resized itself on first boot - these guys have done a smashing job of making it easy to get started!

The developpers have recently created a twitter account (@*RPF_Dev_Updates*https://twitter.com/RPF_Dev_Updates). I believe it'd be nice to cooperate in some way to improve the audio on the Pi. A guy named Dom seems to be responsible for all the audio stuff.
Cheers,

I bought one similar, it look like a proprietary plug dedicated to xbox, that can't be use with a hdmi cable. i'm looking for an other one, or a way to hack this to be pluged in a standard hdmi cable.

So much for 'standards' then! There are HDMI to VGA or Component video adapters that have RCA outputs. Those are more than the XBox ones - $30-40 USD:

Probably something similar in your area.

I just did the git clone, but there is no configure file in pure-data/src
