Do you know if there are any specific HDA controllers and/or codecs that 
work better or worse in this regard? I'd be very interesting to know.
My experience differs from yours - on my HDA here, I can run with 
driver=alsa, 4 x 64 buffers quite stable (as in, if there are xruns, I 
can't hear them). Something I consider OK, especially given the fact 
that I don't run any special rt kernel (just Ubuntu's standard one, 
called "generic"), and haven't done the limits.conf stuff either.
