it can't be fixed. ardour's MTC output stream is bursty and nothing
will ever correctly sync to it. we require usec-resolution timers to
make this work, something that no regular linux kernel has, and that
even with the HRT patch, don't seem to work too well.

to get that work as well as possible, i just need more time at the
studio ironing out the glitches in ardour's slave support.
