Dear all, I just took a quick look at the page on puredata.info and noticed that my soundcard (E-mu 0404 USB) is mentioned as "apparently [working]". For clarity's sake i think it would be good to modify the page a bit so that it's mentioned in the working soundcards. It's fully functional as far as i can tell (it works in duplex at 44100 Hz with one input) and has been since the beginning on the RPi without any slowing down of the USB speed. I can even prove it with a video (http://www.youtube.com/watch?v=NwJNeouLqgQ) ! Problem is, i don't know how to edit the page...
