Comment 19 for bug 276463

Kernel 2.6.32 (2 December 2009) and libraw1394 v2.0.5 (26 December 2009) contain the fixes that are required for FFADO. Debugged and implemented by Jay Fenlason.

I believe I had vanilla FFADO v2.0.0 running with these, but Debian's FFADO maintainer packages FFADO trunk which contains a small fix that is related to the new FireWire drivers. I don't know how essential that fix is. I heard FFADO is going to do a v2.0.1 maintenance release eventually; however, Debian's current FFADO package is closer t what will become FFADO v2.1 --- also to be released "any day now" with much extended hardware support (independent of whether old or new firewire kernel drivers are used).

In short: After storage, consumer video, industrial video, and IP networking, FireWire audio as the last missing piece in the puzzle works through the new kernel driver stack too since end of 12/2009.

Note that Ubuntu's current defaults (old stack, no user access to raw1394) effectively prevents non-experts from using FireWire for anything else than storage devices (and even those with less performance and compatibility than the new drivers offer).
