Here's a quick update on the Fireface-800. The short story is that it mostly works as of svn revision 2062. Ffado-mixer includes all device controls and the matrix mixer is complete. Audio streaming works to and from the device, although startup can still be a little rough (that's next on my list to look at). It's probably ready for an initial round of testing by others to confirm that success can be achieved on systems other than my own. Please use the ffado-devel mailing list to report bugs and provide feedback.
