here is a picture :

but it's very old. i think any usb stereo soundcard (somes are very small) are using the same driver, so they sould work the same.

I'm really interested in the Pi as a very small device for running Pd, and my USB soundcard is good but really big compared to the form factor of the Pi. I'd be interested if anyone has found a soundcard that works well and has the same compact style - the cheap ebay dongle-sized ones may not be so good, but they are small. Does anyone have a good experience with one of these on a Pi or a regular PC machine?
for performances, i'm using soudcard with spdif out (like ua-1X) or maybe this behringer (that i did not try) ,(currently, i'm using the spdif out of my asus laptop):

then, i've got a vc8 fostex DA converter that provide a very good sound.

antoine did successfully use something like this :
