Hi,
I just discovered that linux journal covered rt-audio in one of their
video tutorials. The guy compiles his own kernel and uses some stuff I
haven't seen before, but all in all it doesn't look bad.
Here's the link:
http://www.linuxjournal.com/video/hyper-low-latency-audio-real-time-kernel
And the direct link to the youtube video:

Maybe it's useful to someone.
Best regards,
Philipp
